Welcome aboard Mariah! You have chosen one of the most popular and best equipped boats
in the San Juan Yachting fleet. We have maintained her in a like new condition and are continually
upgrading and adding new features. We trust you will take care of our investment as if she were
your own. Please let us know if you find anything missing or in need of improvement. While using
or reviewing these notes, please feel free to mark corrections, and make suggestions and
improvements. Your constructive criticism will be appreciated. We hope you enjoy cruising with
509-220-8475
INTRODUCTION
Mariah is a 2004 Nordic Tug 42, powered by a Cummins diesel engine, with a HP rating of 450
@ 2600 RPM. It can carry 600 gallons of fuel and 200 gallons of water. At a time when we are
all conscious of high fuel prices, the Nordic Tug provides a real bargain. According to Cummins
Northwest, Inc. data, the 42 Nordic Tug can provide hours of cruising fun at reasonable speeds
with very limited fuel consumption.

NOTE: All system operation instructions assume you have all AC and appropriate DC circuit
breakers powered. Note: Red lettering indicates safety items or key operational notes.
These notes are prepared for Quick Reference. Nordic Tugs, Inc. has provided an operation
manual for the 2004 model. Much of the information is taken from the Tug Operator’s
Manual but has been condensed for quick reference. For more in-depth systems information
please consult the owner’s manuals and component manufacturers’ installation/operation
manuals that came with the boat. They are large red notebooks located under the hinged
instrument panel in the pilothouse. The Owner’s Notes assume that the charter
guest/operator is experienced and competent in the safe operation of a 36,000 pound, 44 foot
powerboat, and knowledgeable of boating rules and regulations. These notes do not attempt
to anticipate every situation or occasion that may arise. Chances are good you will never
have to accomplish any of the detailed procedures we have included in our notes. (i.e.
changing a fuel filter etc). We have included this type of information in our notes to give you
the peace of mind in knowing there are instructions in the unlikely event you should need
them. These notes are not all-inclusive but should be adequate under most situations.
Exercising reasonable care and good judgment in the handling and operation of the boat is
the best way to ensure a trouble-free experience.

9 Key Nuances to remember when operating Mariah
1. Checking the oil: Remember to properly seat all dipsticks after checking oil levels. If not
seated, oil will spray out and make a mess.
2. Securing the tender: When returning the Tender, remember to install the two aft and
one forward tie-down straps and the stabilizer bar if you anticipate heavy seas.
3. Icemaker: To save the batteries, turn the ice maker off when anchored.
4. Connecting to shorepower: Deselect “INVERT” on the Xantrex inverter panel (office
station) when shore power is connected. (Prevents battery depletion if shore power
fails)
5. Electric heaters: Unplug all three electric heaters when NOT connected to shore power.
Otherwise the inverter will attempt to power the heaters and will deplete the batteries
and damage them.
6. Window shades: When raising and lowering the shades in the pilot house, use two
hands pulling in opposite directions on the cords. This will relieve stress on the shade
clutch and mounting assembly. The salon shades are a new style without cords.
7. No metal under office seat: Do not store any metallic items under the office station seat
or on the floor in front of the seat. The ships auto pilot compass receives its directional
input from an electronic compass under the seat. Inputs can be affected by metal
objects in close proximity.
8. Tender drain plug: open the drain plug switch on the steering wheel panel when the
tender is stowed. (Remember to close it before launching the tender). This will help
prevent water buildup and corrosion of electrical components in the tender.
9. Tender outboard: Make sure the outboard motor on the tender is tilted full up and
steering wheel full left. If not, the lower unit will splash seawater into the tender and
can damage the electrical box and connectors. On one occasion a charter guest left it
down and sea water nearly filled the tender requiring a complete rewiring of the
systems. You will never do a starboard docking because the outboard will hit the dock.

PREPARING FOR DEPARTURE
1. ENGINE ROOM CHECKS should be performed daily, before cruising.
At the office station, turn ON the BILGE Lights. Enter the engine room aft of the galley through
a hatch in the floor.
Note: All fluids have been checked by a maintenance professional prior to your
charter and it is very unlikely that these fluid levels would require servicing during
your charter. However, it is strongly recommended that you do a daily engine
room inspection looking for evidence of oil or other fluid leaks.
Check the oil level in the engine. There are 2 dipsticks. One on the port and starboard sides of
the engine. Either one can be checked. The port side is easier to access. The oil level on the
dipstick should be between the hash marks. If the oil level is low:
•Add oil from the blue plastic jug marked Delo 400 15/40 SAE, using the
funnel found in the replacement fluids bin stored in front of the engine.
•DO NOT OVERFILL THE OIL CAPACITY of the engine. It only takes 2 quarts
to fill the oil supply from the lower line to the upper line on the dipstick. You will
likely never need to add oil.
•When replacing the dip stick ensure it is properly seated. (Down to the yellow
tape line.) If not seated, oil will spray out making a mess.
Check the coolant level of the white plastic recovery reservoir mounted on the forward bulkhead
in front of the engine. (aka “plastic jug”) The jug should be half full. If the coolant level is low:
1. Add some pre-mixed engine coolant to the recovery reservoir.
2. The pre-mixed engine coolant marked 50/50 ENGINE COOLANT is located in
the “Replacement Fluids” bin.
Checking the oil level in the generator. The generator has a diesel engine requiring the same
care as the main engine. The generator is self monitoring and will auto shut down for a number of
reasons and provides a sequence of flashing lights that will identify the cause, (see the owners
manual in the pilot house) If low oil is suspected, remove the rectangular panel on the FRONT
SIDE of the generator to access the dipstick. The oil level on the dipstick should be within the
hatch-marked area on the stick. If the oil level in the generator is low:
1. Open the OIL FILL to the side of the dipstick.
2. Add oil from the blue plastic jug marked Delo 400 15/40 SAE, using the funnel
from the bin marked “Replacement Fluids.” Be careful not to overfill.
Check the coolant level in the generator. The generator’s diesel engine uses coolant just like the
main engine. A plastic coolant recovery reservoir (aka “plastic jug”) is mounted on the port side
of the generator. Visually check that the coolant level shows approximately 2 inches when the
engine is cold and 6 inches if hot. If the coolant level in the generator is low:
1. Add coolant to the recovery reservoir to the appropriate level, being careful not to
overfill—the coolant needs an opportunity to expand.
2. Use the pre-mixed 50/50 ENGINE COOLANT located in the bin marked
“Replacement Fluids.”
Check the RACOR fuel filters for water or contamination. Few things you do are as
important to your safety on the water as having uncontaminated fuel going to the engine! As you
enter the engine room look on the aft end of each fuel tank where you will find a RACOR fuel
filter for each tank.
•Make sure both filters are free of contaminants or water. Look through the glass
at the liquid in the bottom of each filter. You don’t want to see contaminants or a

5/7/20
5
separation of fluid in the bottom. (Water is heavier than diesel fuel and will
collect at the bottom of the glass bowl if there is water in the fuel.) IF YOU SEE
CONTAMINANTS OR LIQUID SEPARATION, you want to remove them
without removing all the fuel in the glass bowl:
1. With a collection container in place (stored behind the generator), open
the black drain by partially unscrewing the valve at the bottom of the
glass unit to evacuate just the water or contaminants, and then quickly re-
tighten the drain.
2. If the vacuum gage at the top of the filter approaches the yellow range at
cruise power, the filter should be changed. Please advise San Juan
Yachting if you should observe this condition.
3. The Generator has two fuel filters. One mounted on the aft port bulkhead
and the other on the engine itself. The are changed out each season and
require no other maintenance. Spares are available in the spares bin if
needed.
Complete a visual check of the engine room for leaking oil, fuel, or coolant, loose items that
should be secured, or anything unusual.
Verify that all seacocks are open, especially the main engine cooling seacock. They should be
in the open/vertical position.
Make sure that the SEAWATER STRAINERS for the engine and generator are free of
seaweed or debris. The engine sea strainer is a large bronze unit with a glass-enclosed section
that houses a strainer. It is mounted aft of the engine near the engine room entrance and is
connected to the seacock with a large black hose
1. Using the flashlight, which is stored in an open box on the aft bulkhead next to
the toolbox, check to see if the strainer is clear and not plugged with seaweed or
debris before every start.
2. To clean the strainer, close the seacock (lever horizontal), unscrew the top with
the flat bar laying next to the yellow tool box, lift out the basket, swish it back
and forth in the orange bucket filled with clean water, and then reinstall it. There
is an orange bucket in the lazarette that can be filled with clean saltwater. Use
the bucket to prevent dropping the strainer overboard!
3. REOPEN THE SEACOCK!!
4. Note: We have rarely experienced the need to clean the strainer. Avoid
driving through large patches of sea grass and you should be fine.
5. Make sure that the seawater strainer for the generator is free of seaweed or
debris. Use the same procedure as above. It is a smaller unit similar to the
engine strainer and is located on the left side (facing aft) of the generator.
6. Remember to REOPEN THE SEACOCK!!
When you have completed the engine room checks, turn off the engine room lights at the office
station breaker panel labeled BILGE LIGHTS. Failure to do so may needlessly deplete the
batteries.
DISCONNECT SHORE POWER
1. At the OFFICE STATION breaker panel, turn OFF the main AC gang breaker labeled
SHORE POWER. All remaining AC breakers may be left on.

5/7/20

2. On the dock, first turn OFF the shore power circuit breaker at the pedestal, and then
disconnect the yellow electrical cord from the dock power.
3. On the boat, disconnect the yellow electrical cord and store the cord coiled in the cord
bag in the Lazarette. Caution: Always DISCONNECT from the SHORE-END and ---
CONNECT from the BOAT-END---to avoid moving a LIVE cord!
TURN ON DC/BATTERY POWER
Battery power should automatically be supplied to the DC systems when you disconnect
AC power provided the DC breakers are on. All DC breakers may be left on with the
exception of the following breakers that should be turned on only when using that system and
when done turn them off.
1. BILGE LIGHTS
2. SEA WATER WASHDOWN
3. OIL CHANGE PUMP.
CLOSE ALL PORT HOLES AND HATCHES that might permit water to enter the interior,
especially during rough seas and windy conditions.
CHECK AROUND THE BOAT
Review the exterior area around the hull to confirm that there are no obstacles in the water or
loose items that should be secured.
HELM CHECKLIST
Check the fuel level at the “Tank Tender” gauge at the helm, and / or the sight tubes on the fuel
tanks. The tanks should be full on day one.
See fueling instructions below if fuel is needed.
Check the water level.
1. Insert the key in the ignition slot and turn to the ON position. Note the water level on the
gauge at the office station or the sight tube on the water tank in the lazarette, then TURN
THE KEY OFF!
2. See instructions below for adding water, if necessary.
Check that all breakers at the helm station are on except the 3 SPARE breakers and the
WINDLESS, FUEL TRANSFER, DC REFRIGERATOR (top deck freezer) and CAMERA
breakers. Turn the windless breaker on only when you use the system then turn it off for
safety.
Note: The Aft Camera and DC Refrigerator (top deck freezer) and fuel transfer should be off
unless you plan to operate those items.
Start up the Ray Marine depth sounder by pressing and holding the button in the lower left-
hand corner of the screen until the screen comes on.
Turn on the Ray Marine GPS chart plotter by pressing and holding the red PWR button for 3
seconds, the display will comes on after a brief period.
There are two Radar units, the primary radar is viewed by selecting a radar display page on the
chart plotter and following the start up instructions displayed there. The unit mounted left of the
chart plotter is a back up GPS chart plotter and radar. Use it only if there is a problem with the

5/7/20
7
primary chart plotter. If both units are on it creates a low voltage condition and one or both units
may not be fully functional.
Turn on a VHF radio. (two VHF radios are installed)
1. Check the weather channel.
2. Turn on Channel 16.
GETTING UNDERWAY
Make sure that the shift lever is in the neutral position.
Turn the start key to ON. An alarm will sound (low oil pressure). Wait for the engines air heater
to preheat the air. The voltmeter will drop below 12 volts while the system operates (about 15
seconds). When the voltage returns to 12 volts the preheat cycle is complete. (The oil light may
come on but should go out once you start the engine.)
When preheating is complete, push the START button while the key is in the ON position to
start the engine. Note: “Do not crank engine for more than 30 seconds, wait 2 minutes to allow
the starter motor to cool down before restart attempt.”
Let the engine idle for about 5 minutes or until the engine coolant temperature gauge reads above
100. Note: During warm-up at idle, the voltmeter will register about 12 volts. The temperature
indicator will not show any indication of heat until the engine has been running for several
minutes. Keep the engine below 1000 RPMs for five minutes, as the preheater cycles on and off as
needed during this time period. RPMs over 1000 block the preheating function.
Turn on the bow thrusters by pushing the 2 ON buttons simultaneously. The amber light
between the buttons will come on. Toggle the joysticks momentarily in both directions to
ascertain that the thrusters are functioning properly.
1. The thrusters are used primarily in maneuvering at or near the dock. In open
water while underway, the thruster is not effective.
2. The thrusters will turn off automatically after a period of non-use. Restart in the
same manner.
3. The thrusters may overheat and stop after 3 minutes of continuous running. After
a brief cool-down period, they will reset.
4. If a thruster is inoperative, check the large red shut off switch in the lazarette for
the (stern thruster) or the red shut off switch located under a panel beneath the
mattress in the master stateroom for the bow thruster.
Check wind and current directions.
Use the thrusters to control the movement of the bow and stern while operating the throttle in
short applications of forward or reverse, pausing in neutral, as you maneuver in the marina. Note:
when using reverse, the STERN WALKS TO STARBOARD.
CRUISING
When clear of the marina, make sure all mooring lines, fenders and anything loose are stowed.
Operate the engine at 1000 rpm for warm up. (5min.)
1. After a 5 min. warm up operate the engine no faster than 1300 rpm until the coolant
temperature reaches 140 degrees. You will probably operate at 1100 to 1350 rpm, as this
is very economical and quiet. 1350 rpm is the “sweet” spot. Above that setting fuel burn
goes way up without much corresponding speed increase.

5/7/20

2. Please make power changes slowly, rapid power changes can put great stress on engine
and drive components. It is advisable after cruising for 4 hours or more at economical
speeds (1100 to 1500 RPM), to run the engine at 2400 RPM for at least 5 min. prior to the
end of the cruise day. This helps to clean out carbon deposits in the engine. At the end of
the run-up slowly and smoothly reduce power as you approach your destination and allow
at least 5 minutes for cool down before shutting down.
3. According to Cummins Northwest, Inc data, at reasonable speeds the Nordic Tug 42 has
very economical fuel consumption.

4. Monitor the engine instruments at the helm station while cruising.
5. Volts should read between 13 and 14 at normal cruising.
6. Water temperature should be between 160 and 165 degrees.
7. Oil pressure should range between 30 and 100 depending on RPMs.
8. Vacuum gauges for the RACOR fuel filters should read below 7 while cruising.

*** RAW WATER ALARM***
Mariah is equipped with a raw water alarm located at the helm. The alarm will activate a
light and a horn when the temperature of the wet exhaust pipe starts to increase toward and
unsafe level. This could occur if the seawater intake or the sea strainer become clogged
with vegetation or other debris. The alarm will trigger before other indications of overheat
occur thus saving costly engine damage. If the alarm sounds and you are not threatened by
immanent grounding, shutdown the engine and investigate.
1. Check the sea strainer and clean if required.
2. Attempt to operate the boat at a reduced rpm.
If the alarm continues it may be a failed raw water impeller. This is unlikely as they
are replaced annually. However, should it fail, there is a replacement
impeller in the spares bin in the engine room. Call San Juan Yachting on your cell
phone or VHF channel 79a and request assistance. The tender can be launched and
used to tow Mariah if there is no other option.
RETURNING TO DOCK
Fenders out and….
•On docking side of the boat, (port side is only used because of the dinghy
outboard)
•At appropriate level for the dock.
The engine cool down period (the last 5 minutes) should be at slow speeds to allow the engine to
cool down before shut off.
1. Once docked and the mooring lines are secure, turn off the engine.
2. Shut down the Ray Marine multifunctional displays by pressing the red power button
in the lower left corner and holding for the countdown on the screen. Please re-place the
screen covers on all the screens as direct sunlight can damage them.
3. There is no need to turn off the breakers at the DC POWER breaker panel next to the
helm station. Do not shut down electronic equipment ie. Chart plotter or depth sounder
with the circuit breakers...use the red power buttons or damage could occur.
•Note: The autopilot wireless remote control is recharged by a cord located below
the dc power plug on the starboard side of the instrument panel. The battery
charge state of the remote can be read on the left side of the screen and is
represented by a number of bars. The autopilot c/b must be on for power to
charge the remote. Depending on use, one charge should last 2-3 days.
Remember to turn the remote off by pressing and holding the © button while the
unit counts down. Use the same button to turn the unit on.
•CAUTION: If using the remote outside of the pilothouse please use the attached
lanyard and wear it around your neck. The remote costs over $400 and could be
easily lost overboard.

CONNECTING TO SHORE POWER
1. At the OFFICE STATION electrical distribution panel, make sure the AC gang circuit
breaker marked SHORE POWER is in the OFF position.
2. Take the bright yellow electrical cord located in the Lazarette and connect it to the
receptacle located forward of the starboard helm door. Line up the prongs, insert the plug,
turn it to tighten.
3. Locate the power supply on the dock; making sure that the breaker on the dock is in the
OFF position. The yellow electrical cord is 30 amps. Check the amps for the shore power
pedestal on the dock, and use an appropriate adapter, if necessary. (a 30 to 20 and 30 to
15 amp adapters are stored in the cord bag in the lazarette. Connect the electrical cord to
the dock power source, matching prongs, twisting, and tightening. Then turn the dock
power source ON.
4. Return to the boat and turn the AC SHORE POWER circuit breaker to the ON position.
5. Verify that you have power to the main electrical distribution panel by looking at the AC
voltage gauge on the SHORE POWER OR GENERATOR distribution panel.
6. All AC circuit breakers should be ON.
NOTE: 30-amp power may not be sufficient to run all the ships systems if the batteries are not
fully charged when connecting to shore power. . The inverter/charger will draw a large amperage
to charge up the batteries and may cause the dock power to disconnect. You may not be aware of
the disconnect because the boats dc system (lights etc) will still be on and the batteries will be
discharging. To prevent this condition, check the AC panel voltmeter at the office station at least
5 to 10 min. after shore power is applied. See if the meter shows that 110/120 volts are available.
If the AC voltmeter is not illuminated, then you have lost AC power. To regain power and
download the AC system, turn off the water heater, and any electric heaters. Check the inverter
control panel at the office station and using the power share button, select a battery charge rate of
15 or 5 amps. This will allow more power to be diverted to ship systems like hot water or electric
heaters. Turn off the Shore Power breaker and go to the dockside power box and reset the
dockside breaker. You may also try another outlet in case you have a weak breaker with the first
outlet. Return to the boat and restore AC power with the Shore Power breaker. This procedure
will be even more important if you are limited to 20 or 15 amp dockside power, which is common
at smaller marinas in Canada. Remember to recheck that AC power is still connected after 10
minutes, if not reduce the load more. The most important thing is to keep the batteries charged.
As the charge level comes up the inverter/charger will draw less power and enable you to turn on
other systems like the water heater and / or electric heaters. The bottom line is if at any time you
need more AC power than is available you can start the generator, which at 11.5 KW can operate
all ships systems and recharge the batteries simultaneously. (See generator operation).
SAFETY NOTE: Any time you are connected to shore power be sure to deselect the inverter
(green LED light “not illuminated”) on the xantrex control panel. Failure to do so could rapidly
discharge the batteries, as the inverter will attempt to run the entire electrical load including
heaters if shore power should fail. For the same reason ensure all electric heaters are unplugged
before disconnecting from shore power. If you need heat, start the furnace!

CLOSING THE BOAT
1. Close windows and hatches. Close all shades in pilothouse and both port and starboard
sides of boat. (To prevent sun damage to the interior).
2. At the DC POWER distribution panel (Office Station)
•Ensure the inverter power button is off. (No green light illuminated on the
INVERT button at the xantrex control panel).
•Leave the DC POWER circuit breakers ON except for the red flagged breakers.
•Turn off the water heater breaker on the A/C panel.
3. Lock the doors.
4. On the dock, check the position of all fenders and see that mooring lines are secure.
ELECTRONICS
1. Ray Marine Radar, Chart-plotter, Depth/Fish finder.
Note: For more detailed instructions on the operation of these units please
view the DVD video I have prepared. (located in the entertainment cabinet)
Mariah is equipped with the latest Ray Marine electronic equipment, and with Multi-Dimensional
Charts for the Pacific Northwest to Alaska. The display includes navigational charts, 3-D
displays, Fish finder, Radar, Data, Course Deviation Indicator and Waypoints capabilities. Please
refer to the Quick Start Card, Operating Guide and Reference Manual, which is on-board. You
will use the chart plotter any time you are underway. It is a wonderful tool and confidence
builder and should be used in conjunction with paper charts. Most of the time we operate with 2
map displays open. One window will be zoomed in for more detail, the other window will be
zoomed out for a bigger picture of the area you are navigating. To change the scale on either
window, press the “active” button. That will activate a screen and give it a red boarder line
around the screen. Then press the “in” or “out” button to zoom in or out. The red border
indicates the active window and can be modified with the zoom feature and other ways. Your
check-out skipper will show you the basics on the chart plotter. Use the manual for more detailed
functions if you wish. New for 2017 we have added an additional touch screen multifunction
chart plotter and additional radar as a backup to the primary plotter and radar. The operating
instructions can be selected from the home screen. If both chart plotters are on at the same time
you will not be able to engage tracking to a waypoint with the center (main) chart plotter through
the autopilot. You must control engagement of tracking with the smaller touch screen unit on the
left side. For simplification reasons we suggest using the touch screen unit only as a backup
should the main unit or its associated radar fail for some reason. Do not use the circuit breakers to
turn off the helm electronics units, they are like computers and need to be shut down and started
with their own power button on each unit. Please do not attempt to remove the navigation card in
the chart plotter. If not done properly the card can become corrupted and henceforth unusable.
Also do not operate both chart plotters simultaneously as it will create a low voltage condition
and will shut down one or both chart plotters. Use the smaller plotter only if a failure should
occur on the primary unit.
Mariah has a custom Bose AM, FM, CD, DVD, TV video, Player with surround
sound and Bluetooth capability.
2. Using Direct satellite TV and radio.
To use the Direct TV programming:

5/7/20
12
a. First turn on the flat screen TV with the LG TV or the Direct TV remote.
b. Turn on the Trac-Vision power switch located on the upper right corner of
the inverter/waste panel at the office station. The Trac-Vision unit makes a
grinding sound as it searches for a satellite. The sound is normal.
Make sure the dish receiver is on, and monitor the progress on the TV
screen as the dish acquires the satellite. If the satellite fails to lock on after several
minutes, try disconnecting the power by pulling on the power cord closest to you
on the power strip for 20 seconds. Then reconnect power. The receiver will
re-boot and may solve the connection problem.
c. Use the Direct TV remote to change channels and the guide button
to view program options just like you do at home. You can also use this
remote to control other components by selecting them with the selector
at the top of the remote.
•Select video 1 on the BOZE remote and use it for volume control.
•If you are not connected to shore power you will need to use the inverter
to power these systems. Remember to turn the Trac- Vision and inverter
off when not required, in order to save battery power.
* Streaming music and audio from your personal device
There is a Bluetooth (esinkin) devise on the left side of the Bose receiver in the
entertainment cabinet. Turn on your device and go to the Bluetooth page, then press the
button on the esinkin and it will pair to your device and allow you to listen to your own
music or audio channels. Note: use the AUX position on the Bose unit to hear your
audio.
FUEL
Mariah has two (2) diesel fuel tanks located on the port and starboard sides of the engine room,
under the salon. The fuel transfer manifold is located in the engine room on the aft bulkhead port
side.
CHECKING THE FUEL LEVEL
1. At the “Tank Tender” gauge at the helm, toggle the switch to port and starboard to check
tank quantities. The ignition key must be on to power the gauges.
2. The most accurate method is to view the sight tubes on the tanks.
FILLING THE FUEL TANKS
The fill caps for the diesel fuel tanks are located starboard and port of the helm station doors. Fill
on BOTH sides. On the starboard side, the WASTE cap is next to the DIESEL cap—DON’T mix
them up! They are marked.

5/7/20
13
Before you start to fuel:
1. Make sure the engine is shut down, the furnace is off, all ignition materials have been
extinguished, and everyone else is off the boat. There is a fuel tank vent located just
below the fuel tank fill. Usually the fuel attendant has an overflow device to attach below
each vent to catch any spillage—but if the attendant doesn’t, hold an absorbent pad under
the vent if you intend to fill to the maximum level. (not recommended)
2. Fueling can be messy: take an absorbent pad, rag, and/or paper towels from the galley to
have at the ready. Clean any fuel spill off the deck--- it is slippery and hazardous.
3. Open the DIESEL cap with the spanner wrench/key located in the chart drawer at the
helm. There should also be one hanging on an emergency transmitter mounted in the
salon next to the entry door. Have a crewmember remain in the engine room and monitor
the filling with the sight tube. (Be sure to open the two valves on the sight tube to get an
accurate reading, close when done). Fill until you can see no air in the tube and repeat
this procedure for the other tank. This will prevent an overfill condition and you will be
returning the boat with visually verifiable full tanks as they were when you began your
trip.
4. Insert the nozzle into the fill port, and then start the flow. When fueling is complete,
remove the nozzle from the fill port, immediately screw the fill cap back in place to
ensure no contaminates get into the tank, Use the same procedure for the opposite fuel
tank, then return the fuel nozzle back to the dock, and return the key to the drawer in the
helm.
SERVICING THE FUEL FILTERS
Few things you do are as important to your safety on the water as having uncontaminated fuel
going to the engine! Mariah is equipped with two RACOR fuel filters. (One filter for each tank)
and are located aft of each fuel tank in the engine room. A vacuum/pressure gauge is read at the
top of each filter.
Check the two fuel filters for contaminants or water as part of the pre-cruising engine room
check. If there are contaminants or a separation of fluid in the bottom of the glass collection
containers, they should be drained of the contaminants:
-With a collection container (behind generator) in place, open the black drain at the bottom of
the glass container by partially turning the valve; retighten the valve when the water or
contaminants have been drained and at least 8 oz. of fuel have drained. (8oz will avoid a spill
when you change the filter). You may dispose of the drained fuel in the waste oil container
found behind the generator.
Replace the RACOR fuel filter if the pressure gauge reads between 7 and 10.
The two RACOR fuel filters located in the engine room have a vacuum gauge read when the
engine is running at cruising speeds. The RACOR Company instructions say when the needle on
the vacuum gauge reads between 7 to 10 inches (of vacuum) it is time to replace the filter
element. The elements are changed routinely, but you never know when water or contaminants
will get into the fuel tank, so be prepared to change out the filter if the vacuum gauge is reading
between 7 and 10 inches! The replacement RACOR 2-micron filters are located in the black
plastic bin in the engine room. Labeled SPARE PARTS, AND FILTERS.
1. Change the filter with the reading between 7 and 10 inches of vacuum. If both indicate in
this range than change them both.
2. First, drain out a few ounces of fuel using the drain valve and catchment container.

3. Remove the lid of the filter to be replaced by turning/loosening the tall brass nut located
at the top of the filter unit. Remove the filter element by holding the molded handles on
the filter element and slowly pulling upward with a twisting motion.
4. Replace the black lid gasket with a new black lid gasket supplied with the new filter.
Apply a coating of clean fuel or motor oil to this gasket seal prior to reassembly. Insert
the new filter (with labeled end up) with a slow downward twisting motion.
5. Fill the filter unit with clean diesel fuel by slowly pouring it on top of the filter element.
Clean diesel fuel is located in the “spare parts and filters bin” in the engine room, in a red
gallon jug marked “Diesel Fuel”.
6. Replace the red O ring on the tall brass nut shaft under the lid with the new red O-ring
provided with the new filter element.
7. Then put the lid back on the unit and snugly tighten the brass nut by hand- ONLY.
8. Start the engine and check for leaks. Correct any leaks with the engine off.
9. Remember to replenish the jug of clean diesel fuel at the earliest opportunity
4. FUEL TRANSFER
At times you may notice the boat is listing slightly to port or starboard. The list may be caused by
an imbalance of fuel in the two tanks. You can verify a fuel imbalance by observing the fuel tank
sight tubes in the engine room. If one tank has a significant difference in fuel level compared to
the other, you can use the fuel transfer system to balance the fuel load. To transfer fuel, you must
first turn on the guarded fuel transfer circuit breaker located at the bottom of the helm breaker
panel. For example, if the starboard tank level is higher, move the top toggle switch on the fuel
transfer panel (near the throttle) to the right and the lower switch to the left. This action will burn
fuel from the right tank and return the excess fuel not required by the engine to the left tank.
Reverse this procedure if the left tank level was higher. To prevent inadvertent venting of fuel
overboard please observe the following guidance.
1. Do not attempt to transfer fuel unless you can see at least a six-inch difference between
the tank levels.
2. Check the transfer progress at least every 20 minutes by comparing the fuel tank sight
tubes in the engine room.
3. Stop the transfer if you can no longer see air in the sight tube of the tank you are
attempting to fill. You may have transferred beyond the sight tube limit and could start
venting fuel overboard!
4. Terminate the transfer by moving both transfer toggle switches to the center position and
remove power with the guarded fuel transfer circuit breaker. This will prevent
inadvertent transfer of fuel caused by bumping the switch.
Note: You can also attempt to equalize the fuel load using gravity by opening both cross-over
valves at the forward end of each tank. This is the simplest way but will not allow you to to use
the fuel as a means to fine tune any listing that may be present.
WATER
There is a 200-gallon fresh water tank on Mariah. The tank and shutoff are located in the
lazarette.
CHECKING THE WATER LEVEL

5/7/20
15
The gauge for checking the water level is located at the office station. The ignition switch must
be on to power this gauge. You may also check the sight gauge on the tank located in the
lazarette. Just like the fuel tanks....the sight gauge’s are the most accurate method.
FILLING THE WATER TANK
1. Locate the deck plate marked “WATER” on the cockpit floor just outside of the salon
door. The deck plate key to open the plate is located in the chart drawer in the helm.
2. Connect the WHITE fresh water hose (located in the lazarette under the cockpit) to the
domestic water supply at the dock. Let the water run through the hose (overboard) for a
minute or two to wash any contaminated water from the hose. DO NOT USE THE
HOSE AT THE DOCK TO FILL THE WATER TANK—YOU DON’T KNOW
WHERE IT HAS BEEN!
3. Fill until the filling sound starts to increase, or water comes out the vent/overflow on the
hull just below the deck fill.
4. Tighten the deck cap.
5. Return the deck cap key to the chart drawer in the helm.
HOT WATER
Hot water is provided by an 11gallon tank heated electrically and by a heat exchanger from the
engine. You automatically have hot water if the engine has been running. When connected to
shore power, or using the generator, make sure the WATER HEATER circuit breaker on the AC
POWER distribution panel is in the ON position. If you are anchored out for a time and need hot
water you must start the generator and ensure the hot water breaker is on. After 20 to 30 minutes
you should have plenty of hot water.
ICE MAKER
The ice maker can be used when connected to shore power, or when underway through the
inverter. Our recommendation is to make ice during the above periods and transfer it to the
freezer. Turn the icemaker off when anchored as it is a significant drain on the batteries.
ELECTRICAL POWER
DC/BATTERY POWER
The BATTERY POWER or distribution panel is located on the right half of the main circuit
breaker panel at the office station.
1. The DC POWER circuit breakers should be left ON, whether you are on or off the
boat, and regardless of whether you are connected to shore power or running the
generator. EXCEPTION: leave the following breakers off until you need to use the
system: 1) BILGE LIGHTS. 2) OIL CHANGE PUMP. 3) SEA WATER WASHDOWN.
2. If you have been plugged into shore power for 12 or more hours, the batteries should be
charged. Away from shore, as long as you are cruising several hours a day, the batteries
are recharging, and you should have adequate power without the aid of shore power.
Note: There is a Xantrex battery display at the office station. It measures the state of
charge for the house battery bank. It works in unison with a generator auto-start circuit
that will automatically start the generator when the battery voltage is low or a large draw-
down is experienced such as starting the coffee maker in the morning after having
watched a movie at anchor the night before. When the generator starts on it's own you

5/7/20
16
must go to the office station and turn on the gang circuit for the generator in order to
bring it on line. The Xantrex “Power Share Selector should be set for 50amps to provide
maximum charging from the generator. The generator is preset to run for two hours and
then will shut down. You can always shut it down manually at any time you wish, after
the batteries are recharged. If the DC volts read less than 12.0 volts you will need to run
the generator to recharge the batteries, unless you will be underway soon.
INVERTER/CHARGER
The inverter is intended to provide 110 volt AC power to small appliances when you are away
from shore power, or do not want to use the generator. The inverter converts 12-volt battery
power into 110 volt AC power. The XANTREX INVERTER/CHARGER panel is located at the
office station directly in front toward the left, as you are sitting at the table. While away from
shore power, if you want 110 AC power:
1. Turn the Inverter ON at the INVERTER/ CHARGER panel by pushing where it says
INVERT. A green indicator light will come on inside the box labeled INVERT. With
this green light illuminated, the inverter will power selected 110-volt appliances and
outlets.
2. Confirm that the following circuits on the AC panel at the office station are ON:
•Microwave, Galley Outlets, TV, Head, and Ice Maker (if desired).
3. Monitor your usage.If too many appliances are on at the same time, you may
trip the Inverter/charger breaker on the AC panel. If this happens, unplug or turn off one
or more appliances and reset any tripped breakers on the AC SHOREPOWER panel at
the office station.
4. Do not attempt to power portable electric heaters through the inverter! When AC
power is available from shore power or from the generator, the inverter/charger
automatically charges the house batteries. However, when leaving the boat, go to the
office station and observe the Xantrex inverter panel. Check the green LED light is not
illuminated on the INVERT button. If it is, push the button and the light and inverter
will turn OFF. This should be done so if shore power fails, an onboard appliance (e.g. a
coffee maker, or a heater) will not draw down the batteries. The real danger is that the
bilge pumps depend on battery power, and if they die, the bilge pumps die with them.
GENERATOR
Mariah has an 11.5 kw Onan generator. You may need to use it if you have overnight anchorages
of a day or more and have used the inverter to power AC systems. If you have been connected to
shore power or are running the engine 5-6 hours a day, you should have adequate battery power.
However, if the DC panel voltmeter #2 battery bank (house batteries) gets down to 12 volts, and
you do not plan to be underway soon, run the generator to recharge the batteries. It is harmful to
the batteries to discharge below 12 volts.
Note: If the generator auto start panel is in the “enable” position it will start the generator when
the battery level reaches approximately 11.8 volts. Should the generator start on its own you will
need to go to the AC power panel and select the generator gang breaker to “ON” in order to
charge the batteries. Also ensure the xantrex power-share panel is set at 50 amps for maximum
charging rate from the generator.
1. The generator panel is located in the center/right of the AC panel at the office station.
There is a rocker switch on the left side of the panel used to start the generator engine.
Hold the top of the switch DOWN in the Start/Preheat position for approximately 10 to
20 seconds. When preheat is complete the engine will start and you can release the

5/7/20
17
switch. If there are no illuminated lights in the switch when pressed, ensure the (red
rocker power switch) on the upper starboard side of the generator unit is turned on. (That
switch can easily be pushed off inadvertently when moving about near the generator). If
the engine fails to start with the first attempt, be sure that it has stopped completely
before re-engaging. Do not crank the starter for more than 20 seconds consecutively. If
the engine fails to start, consult the Operator’s Manual under the tip up instrument panel
in the pilot house.
NOTE: If the generator start circuit is completely inoperable it is most likely because
the ON/OFF switch and/or the generator breaker is off. They are both located on the
generator itself in the engine room. These switches can easily be bumped when in the
engine room and will completely cut power to the starting circuit.
2. Let the engine run for 2 minutes to warm-up before adding an electrical load.
3. After the warm-up period, turn ON the generator circuit breaker at the SHORE POWER
OR GENERATOR distribution panel on the upper left side of the AC panel. Slide the
blocking panel up, and then move the generator circuit breaker to the ON position. Note:
The blocking panel will not allow you to engage the generator unless AC Shore power
breaker is first turned off.
4. Select the desired circuits which you want the generator to operate and move them to the
ON position.
Note: The Inverter and Battery Charge breakers need to be ON to charge the batteries.
Beware, the breakers may trip if using too many high amp appliances in the galley. The
toaster and coffee maker together may trip the breaker and terminate battery charging
even when the generator is still running. Check the breakers from time to time when
operating galley appliances.
5. Monitor the generator control panel for any faults that may occur and are indicated by a
series of flashes in the switch.
6. To shut down the generator
7. Remove the electrical load –Turn OFF the generator circuit breakers at the
SHOREPOWER OR GENERATOR distribution panel at the upper left side of the AC
panel.
8. Run the generator 2 minutes to cool down.
9. Push the lower rocker switch down to the STOP position.
Note: you will need to start the generator if you want to use the dryer as it requires 220
volt power. The washer will work with shore power or the generator.
TOILETS
Mariah has two toilets commonly referred to as “heads” in the marine world. Each head has its
own enclosed shower, vanity, and sink. One is located in the master stateroom and the other
across the passageway from the guest stateroom. Both heads use a VACUFLUSH freshwater
system, which helps to eliminate odors often emanating from salt-water toilets. The
VACUFLUSH system flushes into a 45gallon-holding tank. The holding tank can be emptied at a
pump-out station, or can be pumped overboard through a macerator pump, and a seacock in the
bottom of the hull, (if you are in a legal zone to do so).
USING THE HEAD
1. In the head, there are 2 panels on the lower cabinet:

5/7/20
18
2. Check the VACUFLUSH panel to make sure the green light is ON –under normal
operating conditions the red lamp will light for 1 minute after each flush until the pump
recharges the vacuum to proper operating level, then the green lamp will light.
3. Check the TANKWATCH panel at the office station daily to make sure the holding tank
light is NOT “red” or full. NOTE: The DC Macerator breaker must be on to power the
indicator lights. Lift up on the foot-operated lever of the toilet to “Pre-Fill” the bowl if
there is not already some water in it. It typically uses one pint of water per flush, but more
water can be added if desired by lifting up on the foot lever.
4. DO NOT PUT ANYTHING DOWN THE HEAD THAT HAS NOT BEEN EATEN
FIRST. Please, NO tampons or other feminine products, no hair, no Kleenex, etc. use
the wastebasket with disposable plastic bags (under the sink) to dispose of these items.
RV or MARINE TOILET PAPER IS THE ONLY EXCEPTION! As it is designed to
break up and dissolve in water. Mariah is supplied with this type of paper. Should you
run out, please get more at the nearest marine or RV store. It is prudent to minimize the
amount of marine toilet paper put in the head. If possible, use the wastebasket. A
plugged up waste system can ruin an otherwise great cruise.
5. Step down on the flush lever for 2 seconds to empty the bowl. If the flush lever is
accidentally released before waste clears the bowl, do not attempt to flush the toilet again
until the vacuum pump stops running (about 30 seconds) and the red light goes out.
CLEANING THE HEAD
There is a toilet brush next to each toilet bowl. Use liquid dish washing soap and water for
everyday cleaning of the toilet bowl. Never use chlorine-based cleaners, caustic cleaners,
chemicals, drain openers, alcohol, solvents, etc. in the system.
MONITORING THE HOLDING TANK
The holding tank should be monitored daily. The TANKWATCH monitor panel is located at the
office station on the inverter/waste panel directly forward from the seat. The gauge will register
the level of the contents of the tank: green for empty, yellow means low, amber indicates mid
level, and red means the tank is full—DO NOT ADD MORE.
DISCHARGING THE HOLDING TANK
The WASTE fitting is located just outside and aft of the starboard helm door. Therefore, you will
want a starboard-side pump out, if at all possible. If you must empty the holding tank from the
port side, taking the waste hose through the helm station, please place throw rugs, plastic bags, or
paper towels through the helm, including over the thresholds, to protect the surfaces from the
dirty pump-out hose and any potential spills.
This can be a messy job—there is a box of disposable rubber gloves and clean-up rags in the
engine room.
To empty the holding tank at a pump-out station or at a portable holding cart
1. Locate the deck fitting labeled “WASTE” just outside the starboard helm door.
2. Open the deck fitting with the key located in the helm drawer.

5/7/20
19
3. Push the pump-out nozzle into the WASTE deck fitting and hold the nozzle securely to
create an airtight connection to allow the contents of the waste tank to be vacuumed out
of the holding tank.
4. Follow the instructions at the pump out station to pump out the holding tank.
5. To rinse the waste holding tank after emptying:
6. Add a few gallons of fresh water through the WASTE deck fitting with the available
fresh water hose from the dock. (DO NOT USE Mariah’s WHITE FRESH WATER
HOSE.)
7. Reinsert the pump-out nozzle into the boat’s WASTE deck fitting and pump some more
liquid out of the waste holding tank.
8. Repeat this procedure.
9. When the tank has been pumped, check the Tank watch Monitor at the office station to
confirm your success; it should show a green light.
10. Carefully remove the pump-out nozzle and place it back on the portable holding cart or
the pump-out station.
11. Replace the deck fitting and tighten it down with the key.
12. Return the key to the helm drawer.
13. Wipe up any spills on the deck and throw away the used disposable gloves and wipe up
rags.
14. Wash down the fill area on the boat with the fresh water hose.
DISCHARGING THE HOLDING TANK OVERBOARD
This method of discharging the holding tank should only be used in strict compliance with the law.
A thorough understanding of the laws and regulations of overboard discharge is mandatory
before discharging waste overboard. Generally, 3 miles from shore is legal. Confirm that the
SEACOCK IS OPEN BEFORE OPERATING DISCHARGE PUMP (open is the normal
position)
1. Open the hatch to the engine room. The macerator is mounted on the center forward
bulkhead. The waste seacock is mounted on the hull to the right of the macerator and
labeled WASTE. Confirm that the lever is in the vertical position to open the Seacock.
2. Back at the office station, turn the macerator circuit breaker on and then flip the
MACERATOR switch to the UP position. The red light will come on.
3. Watch the tank level monitor to confirm that the tank is empty (green light). Note: it may
take 10 min. or more to pump out a full tank.
4. When finished, flip the macerator switch on the panel to the off or DOWN position.
5. Note: It is easy to forget the macerator is running so keep a crew member there at all
times when dumping overboard and when the green light comes on shut down the
dumping operation. Sometime material can foul the sensor and prevent the green light
from coming on with the yellow light still illuminated. If this happens after 10 minutes of
operation, consider the tank empty. After a while the sensor may clear and will then
show green.
6. If after several minutes of operation, the tank lights do not indicate the tank is being
emptied, there may be a clogged duck bill valve. Consult the video for procedures to
clear the duck bill valve.
SHOWER
USING THE SHOWER
•The shower works like any domestic shower. Except that water drains into a small
holding tank and then is automatically pumped overboard. It is advisable to turn on the

5/7/20
20
exhaust fan when showering to remove moisture from the head. The dryer you can keep
the inside of the boat, the less likely you will have a mildew problem.
HOT WATER
Hot water is provided by an 11-gallon tank heated electrically and by a heat exchanger from the
engine.
1. You automatically have hot water if the engine is running, and it will stay hot for quite
awhile even after the engine is turned off. So if you have been cruising for a couple
hours, you should have abundant hot water after the engine is off.
2. When connected to shore power or using the generator, make sure the WATER HEATER
circuit breaker on the SHOREPOWER OR GENERATOR distribution panel is in the ON
position
DECK WASH
There is a deck wash access port at the bow on the starboard side of the windless and also in the
aft cockpit. Salt water is pumped through the self-coiling hoses (kept with the fresh water hose in
the lazaret or may already be connected for easy access), which you can use to clean the anchor
and chain, or wash dirt overboard through the deck drains. We will usually keep one wash down
hose installed at the bow for convenance in washing down the anchor and chain.
To utilize the system:
1. Plug in and twist the hose into the seawater access point. Turn on the SEAWATER
WASHDOWN C/B on the DC electrical panel at the office station. Seawater should
pressurize the hose and enable you to stand at the bow and use the spray nozzle to clean
the anchor and chain as it comes out of the water. It is best to spray water on the chain
before it gets to the roller so that mud and other debris washes back to the sea and not
onto the deck or in the chain locker.
2. If there is no water flow, check to see that the seawater seacock, located in the engine
room is OPEN. Also, gently tapping on the sea water pump can help dislodge material
and start the pump. Sometimes an airlock will occur preventing the pump to prime itself.
Should this occur, try holding the aft wash down sprayer low to the deck and pull the
trigger…this will aid in priming the pump.
GALLEY
STOVE
To operate the stove:
1. Check the propane tank valve is open. (Tanks are located in the propane locker in the aft
cockpit port side of the salon door.
2. Propane should be available to the stovetop and oven. If DC power has been turned off
and then restored, the alarm in the galley near the floor will chirp. (Propane is
automatically turned off with loss of DC power) You must turn the detector switch off
then on to turn the gas on.
3. The stove is equipped with electric starters, to activate push in and turn the knob until the
burner starts. A safety feature is installed in the event the flame goes out the gas will
automatically stop. To restart, turn the burner off then back on.
