and your passengers is in your hands. Plan your trips carefully. Ensure ample fuel supply and

reserve. Tell someone where you are going and when you expect to return. Keep current charts
onboard. Read and observe USCG boating safety circulars.
Regulations
The USCG is the authority of all the waterways. State boating regulations are enforced by local
authorities. You are subject to marine traffic laws and "Rules of the Road" for both federal and
state waterways, and must submit to boarding if requested by proper authority.
There are many publications available from the Coast Guard concerning regulations and more. For
additional information call the boating safety hot line at 1(800)368-5647.
Equipment
USCG regulations require the following equipment while operating your boat:
Fire extinguisher
Personal Flotation Device (PFD) for each occupant
One throwable PFD
Sound signal device
Navigational lights if operated at night
* Sight signal (flare- night, orange flag- day) when in coastal waters or great lakes.
Anchor and sufficient line
In addition, here is a list of suggested equipment you should have aboard your Pro-Line:
First aid kit and blankets * Sea anchor with line
Mooring lines and fenders * Bailing device
Combination oar / boat hook * Tool kit and lubricant
Spare prop, nut & washer * Spare fasteners, hose clamps, plugs
Spare fuses and bulbs * Binoculars or telescope
Local charts and compass * Water proof flashlight
2 way radio (with proper license) * EPIRB (emergency beacon)
Floating key chain & spare keys * Navigation device
Emergency food and water * Water proof matches or lighter.
Passenger Safety
You are responsible for the safety and conduct of your passengers, make sure:
You instruct passengers on proper use and location of PFD's; children and non
swimmers should wear one at all times.
When underway each passenger is in a safe location, and knows to keep
the boat balanced.
At least one other person knows how to operate the boat in case of
emergency.
They are aware of dangers of the prop, and the possibility of sudden
maneuvers and jolts.
To turn the engine off and remove key when swimmers are near the prop or using the
dive platform.
All stay away from lines under stress should they break and recoil.

Rules of the Road
Know and use the rules of the road, the information here is only a brief overview. For detailed
information contact the USCG.
Audible warning signals:
One short horn blast: starboard course change.
Two short horn blasts: port course change.
Three short horn blasts: astern operation.
Five horn blasts: doubt about previous signal, or danger.
One Five second blast every minute: for fog operation
When overtaking, give- way vessel announces intention with horn blast(s) and waits for same
response, then completes maneuver.
When approaching head on both boats give way after giving appropriate horn blast. (preferably to
starboard).
When crossing a vessel converging from starboard has right of way, port vessel gives way (both
acknowledge with one short horn blast).
Know and observe navigational buoys and markers.
Give way to craft under sail.
Hazardous Conditions
Keep track of weather developments and avoid hazardous conditions if possible. When forced to
operate your Pro-Line in storm conditions:
Wear PFD's
Stow loose gear and equipment.
Place heavy items as low as possible.
Head for the easiest to reach safe location.
Reduce speed. If the boat leaves the water you're moving too fast.
If power fails rig a sea anchor off the bow (an empty ice chest will work).
Stay with boat if it capsizes, unless it is burning out of control.
Alcohol
Don't drink and drive. If you have been drinking have someone drive who has not been drinking.
Never operate a boat under the influence of drugs or alcohol.
Carbon Monoxide
Be aware of and avoid conditions that can cause carbon monoxide poisoning (see USCG boating
safety circular 77). Sources of carbon monoxide include any gas or diesel engine, any flame such
as a charcoal grill, stove or heater. Carbon monoxide can accumulate to deadly levels in enclosed
spaces. Always ventilate occupied areas of vessel with fresh air.

Fire
Be aware of and avoid conditions that lead to accidental fire. Guard against and watch for fuel
spills and leaks. Inspect wiring for damage or exposure that could lead to short circuits or arcing.
Make sure those who smoke are vigilant against their ignition source starting a fire. Don't allow
smoking while fueling. Keep a USCG approved fire extinguisher aboard at all times. Inspect the
fire extinguisher regularly, learn how (and instruct others) to properly use it. Only use water to fight
a fire as a last resort and then only after making arrangements to abandon the boat if a fire should
start and get out of control.
If a fire is burning out of control and you must abandon the boat keep the following in mind:
Abandon the boat into the wind to minimize burn risk from floating fuel.
Wear a PFD unless you must swim under burning fuel.
* If swimming under burning fuel throw a PFD outside of the burning area and swim
under the burning fuel to it..
Flooding
Be aware of and avoid conditions that can cause your boat to flood with water.
Possible causes of flooding include; damage to hull or thru-hull fitting, waves washing into the
boat, water entering cockpit due to improper loading.
If you allow water to enter the boat faster than the bilge pump can expel it, the boat will become
flooded and may swamp, capsize, or sink.
Controls
Pro-Line Boats offer many different engine and drive unit choices, therefore the information in this
manual is general in regards to engine and controls. Refer to the engine/ drive manuals in your
owners packet for additional, specific information.
Ignition
The ignition switch has three positions; off, on, start. To start the engine; attach safety lanyard to
operator, turn the key clockwise against the spring pressure to the start position, as soon as the
engine starts release clockwise pressure allowing spring tension to return switch to the on position.
If the engine fails to start within 5 seconds of cranking, allow the starter to cool 10 seconds and
repeat. For detailed instructions see engine manual.
Choke
The choke is only used to aid in starting a cold engine. Operation varies with manufacture, consult
your engine manual.
Safety Shut Down
The Safety shut down switch shuts off the engine in case the operator is thrown from the boat. To
ensure proper function always attach the lanyard securely to the operator.
Shift/ Throttle/ Trim
Your Pro-line can be ordered with several different shift/ throttle systems. Refer to the owner's
packet to find the manual pertaining to your particular installation.
Steering
Your Pro-line is equipped with a self contained hydraulic steering system. When the steering wheel
is turned the helm pump pumps fluid to the steering cylinder, causing the boat to turn.

Periodically check the fluid level and fill if necessary. Beware of adding to much fluid especially if
the ambient temperature is cold because subsequent expansion
could cause leaking or damage to your system (refer to manual in packet). Every 24 hours of
operation check all nuts, caps, and hose fittings for tightness. Check that the hoses are not chafing,
or kinking on sharp corners. Also check that hose ends are not damaged or distorted by the clamps.
The fluid should be changed yearly under normal conditions, twice yearly for heavy use. Lubricate
and maintain in accordance with manufactures manual.
If your steering does not operate properly first check for; drive entanglements, fluid level, hoses /
fittings for leaks, and / or air in the system.
Instruments
Your Pro-Line's instrumentation will vary from model to model and engine to engine, therefore the
following descriptions are general; refer to your engine manual for specifics.
Fuel Gauge
Differences in temperature, loading, speed and trim will affect the actual accuracy of this gauge in
service. It is important to verify the fuel flow in gal./hr. for your boat and make note of your gauge
position with respect to time for different RPM settings. No gauge can give 100% accuracy. If you
notice unusually high or low fuel consumption, investigate to see if the engine is using more fuel
than normal.
Water Temperature
The water temperature gauge indicates the internal water temperature of your engine. Your engine
is equipped with a thermostat to quickly bring the engine up to its optimum operating temperature
range of 150 to 170 degrees f. All outboard engines are also equipped with an audio alarm system
indicating an overheat condition. If the gauge or alarm indicates an overheat condition,
immediately shut the engine off, lift the drive and inspect water intakes for obstructions such as
aquatic vegetation or mud. After finding the source of the overheating, restart engine and confirm
water flow, if water does not flow within five seconds shut the engine off.
Volt
The volt meter indicates battery voltage; normal reading is between 12 to 15.5 volts. A low reading
indicates to heavy of a load or a dysfunction in the charging system. Too high of a voltage indicates
a fault of the charging circuitry and continued operation will damage the battery.
Tachometer
The tachometer indicates the revolutions per minute (RPM) of your engine. Do not operate the
engine beyond the limits stated in your engine manual. Abnormally low tach. readings (for a given
throttle setting) indicates loss of power, or a prop entangled with weeds or trash; check the prop
first. A reading higher than normal indicates a ventilating or cavitating prop, or prop/ drive damage.
Speedometer
The speedometer indicates the speed of your boat in miles per hour (MPH).
The gauge operates by sensing water impact pressure from the pitot tube mounted on the transom.
(or integrated into the lower drive unit of the motor). If the gauge fails to give a reading, suspect a
blocked pickup.
Trim
The trim gauge indicates the in (down) and out (up) position of the drive unit in relation to the hull.
(see Trimming your boat p.27,28 )

Options
Optional instrumentation for your Pro-Line includes: fish locator / depth finder, VHF radio, GPS ,
compass, etc. Refer to the manuals supplied.
Switches
<Fig. 1 helm, 2 switch panel>
Windshield Wiper (optional)
For operation in rain or adverse conditions, optional windshield wipers enhance visibility from the
helm and therefore safety.
Windlass (optional)
Refer to the windlass manual for operation of the optional windlass. The Windlass is protected by a
breaker located on the helm breaker panel.
BilgePump
Your Pro-Line is equipped with an automatic bilge pump system with a manual on switch. The
main pump is located at the aft end of the bilge at the keel. A forward bilge bump is under the
cabin. The automatic float switch is wired directly to the battery terminal through an in-line fuse.
Keep the bilge area clean and free from debris that could clog ports. The helm switch overrides
normal automatic operation. Circuit breakers are located at the helm (and on the transom breaker
box 29w/a & 27 sp). Keep the battery that the bilge pump is attached to charged. If the battery is
discharged and flooding occurs the boat could swamp, causing damage and possible loss of life or
property.

Lights
For operation at night your Pro-Line is equipped with navigation, and anchor lights to indicate your
position to other boaters. While running after dark the nav. lights are required to be on and visible
to other boaters, visually verify operation and lack of obstructions. Lights are also provided for the
cockpit, helm and cabin, as well as spreader lights.
Breaker Switches
The wiring on your Pro-Line is protected by circuit breaker or fuse. If a device stops working first
suspect the circuit breaker is tripped (or fuse blown).
A tripped breaker will protrude from its set position, indicating that the circuit has been overloaded.
Turn off the device(s) on the circuit then reset the breaker by pushing in once. If the breaker does
not reset, or if it resets and then pops out again after the device is turned back on, then a short
circuit exists, or your device may be damaged, overloaded or faulty. Correct the problem and then
reset the breaker. If the breaker continues to pop and you are certain the device, switch and wiring
are in good repair; either the breaker is too small for the load, or is faulty. Reduce the load, or
replace the breaker.

Trim Tabs (optional)
The optional trim tabs operate independently up or down to correct for differing conditions of wind
or load.
Before the boat is underway depress the bottom half of both switches until the tabs are fully
elevated (bow up position) while underway and in open water clear of other boaters, depress the top
half of both switches in half second bursts to achieve the desired degree of bow down trim.
To correct a starboard list give the top half of the port switch a series of bursts until the list is
corrected. To avoid over trim allow a few seconds between bursts to allow the boat to respond (if
you over trim simply give the over trimmed tab a burst or two in the opposite direction).
Warning: trim tabs can cause a dramatic change in the attitude and heading of your boat, adjust
them only when in open water, clear of any obstructions, and then only in small increments.
Systems
Fresh Water System
The water pumps on your Pro-Line are controlled on demand by a drop in water pressure. The
master switch located either at the helm or in the cabin switches the pumps unconditionally off.
The switch should be kept off while not in use, or unattended.
FreshWater
Sea Water System
The bait-well/ wash down switch controls a on-demand pump. Seacocks on all below water line
fittings should be closed when not in use.
Raw water filter, Bilge pump, Seacock (shown in open position), on-demand pump

Head / Waste
If your Pro-Line is equipped with a portable or electric head refer to the manual supplied in your
owner's packet. Do not put anything other than toilet paper in the head or clogging or damage to the
system may occur.
The electric head utilizes a macerator / waste pump and clean-out fittings for dock side operation.
A sea valve is provided for offshore operation. A raw water pump with an intake seacock is used
for flushing.
Electric Head

Fuel / Oil System
The fuel tank on your Pro-Line is made of aluminum with internal baffling to minimize sloshing.
The tank is vented at the fill, inspect the vent for obstructions regularly. 'Deck plate' access ports
are placed over the hose connections and the sending unit. Inspect the hose connections on a
regular basis. If you notice fuel odor or see fuel in the bilge there may be a leak somewhere in the
fuel system. Correct any fuel leaks before operating vessel.
Pro-Line boats equipped with oil injected outboard engines have on board oil tanks located in the
port transom hatch or the bilge. Ensure that the tanks are well stocked with the recommended 2
stroke oil - refer to your engine manual. It is imperative that the oil supply remain clean and
uncontaminated by water or dirt. Check to make sure that the oil lines are free from leaks, kinks,
and chafing.

Direct Current
12 volt direct current provides electrical power for all lighting, refrigerator (12v at sea), pumps,
electronics, and DC devices. A main breaker is located on the transom. Battery selector switches
are on the transom for battery isolation, parallel operation and disconnect. Caution: To avoid
possible alternator / battery damage on twin engine installations, ensure that the optional dual
battery switches are never left so both engines are connected together (never leave a switch on
'both'). The preferred switch position is port engine to port battery, starboard to starboard.

After market Accessories
Your Pro-Line electrical system was designed for factory tested and approved dealer installed
optional accessories. Pro-Line makes no recommendations to the suitability of accessories that are
not listed in the Pro-Line sales literature. Any unapproved modifications or additions to the
standard or optional system are done at the owners risk and may diminish the warranty.
Unapproved modifications could cause risk of fire or failure of the electrical system.
Trailering and Launching
Consult your trailer manufacturer for specific information relating to your particular trailer. Pro-
Line does not make trailers. Make sure the trailer you use is certified.
The use of roller trailers is not recommended, bunk type trailers offer more uniform support.
Consult your state authority for state regulations pertaining to trailering a boat. Use the following
towing check list:
Check brakes if equipped.
Check springs and under carriage for cracks, loose parts and fasteners.
Ensure tires are inflated to proper pressure, and in good condition.
Check wheel bearings and lug nuts.
Verify light and signal operation.
Make sure boat is tied down from bow and stern eyes.
Stow bimini top and other items likely to blow off or out.
Carry a spare tire and tools for changing. (spare bearing and race set for
long trips)
Securely brace O/B motors.
Go slow over bumps.
Check tires and hubs often for excessive heat, service if required.
When backing have an assistant watch blind spots and guide with hand
signals.
Capacity
The trailer you choose should be a proper match for your boat with regard to capacity and hull
design, consult your dealer when making your selection. The tow vehicle must have sufficient
towing capacity for the combined load of boat, trailer and accessories. Check the certification label
on the forward port (left) side of your trailer to ensure that it has adequate gross vehicle weight
rating (GVWR) for the combined boat and trailer.
Hitch
Ensure that the hitch in the tow vehicle is rated for the GTW or greater, and that the ball size
matches the trailer receiver.
Load Distribution
Generally speaking, the tongue weight should be from 5 to 10 % of the GVWR. Make certain that
the hull is evenly supported along the length and width with no load concentrations. Make sure that
the bottom of the transom is supported and not hanging past the end of the trailer. Load the boat so
it is centered side to side, and straight on the supports.
Launching and Retrieving
Pre- Launch Check List-

Install drain plug.
Remove covers and tie downs. (leave bow winch strap in place)
Place lines and fenders if needed.
Disconnect lights to avoid shorting.
Verify that safety equipment is aboard.

Launching-
If possible use a lookout.
Back down the ramp until wheels are under water or the stern of the boat just starts to
float ( keeping perpendicular to the shore).
Loosen bow strap, board the boat, lower the drive unit.
Start the engine and check the bilge for leaks.
Remove winch strap from bow eye.
Back boat off of trailer.
Dock the boat and park the tow vehicle.
Retrieving-
Back down the ramp so trailer is half submerged.
Carefully line up boat, slowly maneuvering with short bursts of power.
When the keel is centered and boat is just touching the trailer, winch (or
smoothly apply power) until the boat eases to rest on the bow rest.
Secure the bow strap.
Haul the boat out of the water and park out of the way of others.
Remove the bilge plug.
Rinse off salt water if fresh water is available (or as soon as possible
otherwise).
Stow equipment and canvas, affix tie downs and covers.
Hook up trailer lights and verify operation.
Operation and Performance
Loading
The capacity plate states the maximum persons and the maximum weight in pounds for persons,
engine and gear that the boat will safely accommodate under normal conditions. These load
capacity ratings are computed using USCG formulas. For operation in rough and adverse
conditions reduce the boats load to permit safe operation.
The performance of any boat is a function of the amount of load carried, great loads reduce
performance. Depending upon conditions and what engine / hull combination you have selected,
your boat may not be able to stay on plane when loaded to its maximum rated capacity.
When loading your Pro-Line always:
Maintain a balance both port to starboard and bow to stern.
Keep heavy items as low as possible.
When boarding, step (never jump) into the boat one at a time.
Pass gear from the dock to someone in the boat, do not carry gear while
boarding.

Never allow passengers to ride with feet hanging over the side of the boat.
Do not allow passengers to sit or stand on top of the stern, or gunwales
of the boat.
Fueling
Due to the explosive nature of gasoline certain precautions must be observed when fueling.
Before Fueling-
Secure the boat to the dock with adequate moorings.
Turn off engine and any equipment having brush type (spark producing)
contacts.
Close cabin, doors, and hatches, so fumes don't enter boat.
Disembark all persons not necessary for the fueling operation.
Prohibit all smoking and open flame on board and nearby.
Have a fire extinguisher close by.
While Fueling-
Keep nozzle in contact with fill opening to minimize chance of sparks.
Do not leave unattended.
Do not spill fuel.
Do not over fill, filling a tank until fuel is vented is dangerous. Allow room for
expansion.
After Fueling-
Close fill opening.
Wipe up any spilled fuel. Properly dispose of rags on shore.
Open cabin door, ventilate boat and run blower (stern drive & inboard)
for a minimum of four minutes before starting.
Check for fumes in bilge, continue to ventilate if present.
Verify proper fuel selector valve position (dual tanks only).
Starting
Follow the information in your engine manual if it deviates from the following instructions.
Before Starting Engine-
Ventilate all enclosed space, and run blower a minimum of four minutes.
Visually inspect bilge for raw fuel, and smell for vapors.
Visually make sure propeller is clear of obstructions or swimmers.
Make sure engine cooling water intakes are submerged.
Lock helm seats to face straight forward.
For a Cold Engine-

Advance the throttle approximately 1/4 open (out of gear).
Activate the choke while cranking.

Release the choke as engine smoothes out.
For a Hot Engine-
Leave the throttle closed and choke off.
* If engine fails to start in 5 seconds, partially open throttle (out of gear)
and try again.
If flooded, keep throttle open for a few minutes and then crank. When
engine starts close throttle smoothly as the engine clears to prevent over
revving.
After your engine starts make sure to observe a few basic rules to ensure that the engine is
functioning properly:
Verify oil pressure and water circulation.
Check the water temperature gauge for the first few minutes to make sure the engine is
warming properly.
Check for leaks especially fuel, shut down and correct if found.
Follow the break- in procedures for your engine.
* After engine is warm and after the necessary break- in, drive the boat at
full throttle for a few moments ( if conditions permit) to verify engine is
developing full RPM.
Torque
The twisting force that the engine applies to the prop lists the hull of your boat in the opposite
direction the propeller is turning. For a large engine or light hull this list can be considerable. A
listing hull has more drag on the side that is deeper in the water causing boat to turn in the direction
of the list. The trim tab on your out drive should be adjusted to counteract the torque steer for the
load and speed the boat is most often operated at. Consult your engine manual for specific
information on trim tab adjustment. Torque induced list can also be corrected by shifting the load in
your boat. Twin engines, when counter rotating, cancel the torque and no correction is required.
Trim
The power trim system allows the operator to raise and lower the drive unit or motor throughout an
infinite number of settings between its upper and lower limits. For every throttle setting there is a
trim setting that will yield optimal speed, stability or maneuverability.
For most conditions the best all-round performance is obtained when the bow of the boat is slightly
out of the water.
General trim down (or "in") characteristics are:
Starting position for best acceleration to plane.
Lowers bow in the water providing better stability and ride in rough water.
Reduces boat speed and economy due to increased drag of hull and drive.
More spray over bow.
General trim up (or "out") characteristics are:
Raises the bow of the boat in the water, resulting in less hull in the water.
Greater speed and economy for a given throttle setting.
Greater maneuverability (provided prop does not ventilate during the
maneuver)
In excess, the reduced stability can lead to bouncing, porpoiseing and
propeller ventilation.

In addition to providing ideal boat performance, the power trim enables the motor or drive unit to
be raised (tilted up) for trailering, beaching, and launching.
The electric motor that drives the hydraulic pump is protected by an internal thermal circuit breaker
that interrupts the power when overheated. Avoid continued pressure on the switch after the unit
has reached the limits of travel (you can hear the difference in sound as the pump strains against the
increased load).
