SAFETY INSTRUCTIONS
ACCIDENTAL STARTING
A WARNING: Accidental starting can cause injury
or death!
• Disconnect the battery cables before servicing the engine/
generator. Remove the negative lead first and reconnect
it last.
• Make certain all personnel are clear of the engine before
starting.
• Make certain all covers, guards, and hatches are
re-installed before starting the engine.
BATTERY EXPLOSION
A WARNING: Battery explosion can cause injury
or death!
• Do not smoke or allow an open flame near the battery
being serviced. Lead acid batteries emit hydrogen, a
highly explosive gas, which can be ignited by electrical
arcing or by lit tobacco products. Shut offall electrical
equipment in the vicinity to prevent electrical arcing
dming servicing.
• Never connect the negative(-) battery cable to the
positive (
+) connection terminal of the starter solenoid.
Do not test the battery condition by shorting the terminals
together. Sparks could ignite battery gases or fuel vapors.
Ventilate any compartment containing batteries to prevent
accumulation
of explosive gases. To avoid sparks, do not
disturb the battery charger connections while the battery
is being charged.
• Avoid contacting the terminals with tools, etc., to prevent
bums or sparks that could cause an explosion. Remove
wristwatch, rings, and any otherjewelry before handling
the battery.
• Always tum the battery charger offbefore disconnecting
the battery connections. Remove the negative lead first
and reconnect it last when disconnecting the battery.
BATTERY ACID
A WARNING: Sulfuric acid in batteries can cause
severe injury or death!
• When servicing the battery or checking the electrolyte
level, wear rubber gloves, a rubber apron, and eye
protection. Batteries contain sulfuric acid which is
destructive.
If it comes in contact with your skin, wash it
off at once with water. Acid may splash on the skin or
into the eyes inadvertently when removing electrolyte
caps.
..
II
TOXIC EXHAUST GASES
A WARNING: Carbon monoxide (CO) is a deadly gas!
• Ensure that the exhaust system is adequate to expel gases
discharged from the engine. Check the exhaust system
regularly for leaks and make sure the exhaust
manifolds/water-injected elbow is securely attached.
• Be sure the unit and its surroundings are well ventilated.
Run blowers when running the generator set or engine.
• Do not run the generator set or engine unless the boat is
equipped with a functioning marine carbon monoxide
detector that complies with ABYCA-24. Consult your
boat builder or dealer for installation
of approved
detectors.
• For additional information refer to ABYC T-22
(educational information on Carbon Monoxide).
A WARNING: Carbon monoxide (CO) is an invisible
odorless gas. Inhalation produces flu-like symptoms,
nausea or death!
• Do not use copper tubing in diesel exhaust systems. Diesel
fumes can rapidly destroy copper tubing in exhaust
systems. Exhaust sulfur causes rapid deterioration
of
copper tubing resulting in exhaust/water leakage.
• Do not install exhaust outlet where exhaust can be drawn
through portholes, vents, or air conditioners.
If the engine
exhaust discharge outlet is near the waterline, water could
enter the exhaust discharge outlet and close or restrict the
flow
of exhaust. Avoid overloading the craft.
• Although diesel engine exhaust gases are not as toxic as
exhaust fumes from gasoline engines, carbon monoxide
gas is present in diesel exhaust fumes. Some
of the
symptoms or signs
of carbon monoxide inhalation or
poisoning are:
Vomiting Inability to think coherently
Dizziness
Headache
Nausea
Throbbing in temples
Muscular twitching
Weakness and sleepiness
AVOID MOVING PARTS
A WARNING: Rotating parts can cause injury
or death!
• Do not service the engine while it is running. If a
situation arises in which it is absolutely necessary to
make operating adjustments, use extreme care to avoid
touching moving parts and hot exhaust system
components.

SAFETY INSTRUCTIONS
• Do not wear loose clothing or jewelry when servicing
equipment; tie back long hair and avoid wearing loose
jackets, shirts, sleeves, rings, necklaces or bracelets that
could be caught in moving parts.
• Make sure all attaching hardware is properly tightened.
Keep protective shields and guards in their respective
places at all times.
• Do not check fluid levels or the drive belts tension while
the engine is operating.
• Stay clear of the drive shaft and the transmission coupling
when the engine is running; hair and clothing can easily
be caught in these rotating parts.
HAZARDOUS NOISE
A WARNING: High noise levels can cause hearing
loss!
• Never operate an engine without its muffler installed.
• Do not run an engine with the air intake (silencer)
removed.
• Do not run engines for long periods with their enclosures
open.
A WARNING: Do not work on machinery when you are
mentally or physically incapacitated by fatigue!

INSTALLATION
When installing WESTERBEKE engines and generators it is important that strict
attention be paid to the following information:
CODES AND REGULATIONS
Strict federal regulations, ABYC guidelines, and safety codes must be complied with
when installing engines and generators in a marine environment.
SIPHON-BREAK
For installations where the exhaust manifold/water injected exhaust elbow is close to
or will be below the vessel's waterline, provisions must be made to install a siphon-
break in the raw water supply hose to the exhaust elbow. This hose must be looped a
minimum
of 20" above the vessel's waterline. Failure to use a siphon-break when
the exhaust manifold injection port is at or below the load waterline will result in
raw water damage to the engine and possible flooding of the boat.
If you have any doubt about the position of the water-injected exhaust elbow relative
to the vessel's waterline under the vessel's various operating conditions, install a
siphon-break.
NOTE: A siphon-break requires periodic inspection and cleaning to ensure proper
operation. Failure to properly maintain a siphon-break can result in catastrophic
engine damage. Consult the siphon-break manufacturer
for proper maintenance.
EXHAUST SYSTEM
The exhaust hose must be certified for marine use. The system must be designed to
prevent water from entering the exhaust under any sea conditions and at any angle
of the vessels hull.

INTRODUCTION
SERIAL NUMBER LOCATION
The engine's model number and serial number are located on
an I.D. plate that is mounted
on the side of the waterjacketed
exhaust manifold.
The engine serial number is also stamped
into the engine block on the fiat surface just outboard
of the
fuel injection pump. Take time to enter this information on
the illustration below. It will provide a quick reference when
seeking technical information and/or ordering needed parts.
HZ.
An identification plate on the engine manifold also displays
the engine model and setial number.
CARBON MONOXIDE DETECTOR
WESTERBEKE recommends mounting a carbon monoxide
detector in the vessels living quarters.
Carbon monoxide,
even
in small amounts, is deadly.
The presence
of carbon monoxide indicated an exhaust leak
from the engine or generator
or from the exhaust
elbow/exhaust hose,
or the fumes from a nearby vessel are
entering your boat.
If carbon monoxide is present, ventilate the area with clean
air and correct the problem immediately!
NOTE: A carbon monoxide warning decal has been provided
by
WESTERBEKE. Affix this decal in a visible position in the
engine room.
UNDERSTANDING THE DIESEL ENGINE
The diesel engine closely resembles the gasoline engine,
since the mechanism is essentially the same. The cylinders
are arranged above a closed crankcase; the crankshaft is of
the same general type as that of a gasoline engine; and the
diesel engine has the same type
of valves, camshaft, pistons,
connecting rods and lubricating system.
Therefore, to a great extent, a diesel engine requires the
same preventive maintenance as a gasoline engine. The
most important factors are proper ventilation and proper
maintenance
of the fuel, lubricating and cooling systems.
Replacement
of fuel and lubricating filter elements at the
time periods specified is a must, and frequent checking for
contamination (that is, water, sediment, etc.) in the fuel
system is also essential. Another important factor is the
use
of the same brand of high detergent diesel lubrication oil
designed specifically for diesel engines.
The diesel engine does differ from the gasoline engine,
however, in its method
of handling and firing of fuel. The
carburetor and ignition systems are done away with and in
their place is a single component -the fuel injection pump
which performs the function
of both.
ORDERING PARTS
Whenever replacement/service parts are needed, always
provide the generator model number, engine serial number,
and generator serial number as they appear on the silver and
black name plate located on the generator end.
You must
provide us with this information so
we may properly identify
your generator set. In addition, include a complete part
description and part number for each part needed (see the
separately furnished Parts List). Also insist upon
WESTERBEKE packaged parts because willfit or generic
parts are frequently not made to the same specifications as
original equipment.
SPARES AND ACCESSORIES
Certain spares will be needed to support and maintain your
WESTERBEKE generator. Your local WESTERBEKE
dealer will assist you in preparing an inventory
of spare parts.
See the SPARE PARTS page in this manual. For Engine and
Generator Accessories, see the ACCESSORIES brochure.

DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
DIESEL FUEL
USE A DIESEL FUEL WITH A CETANE RATING OF #45 OR HIGHER.
(No. 2-D (SAE J313) diesel fuel according to ASTM 0975).
Care Of The Fuel Supply
Use only clean diesel fuel! The clearance of the components
in your fuel injection pump is very critical; invisible dirt
particles which might pass through the filter can damage
these finely finished parts. It is important to buy clean fuel,
and keep it clean. The best fuel can be rendered
unsatisfactory by careless handling or improper storage
facilities.
To assure that the fuel going into the tank for your
engine's daily use
i~ clean and pure, the following practice is
advisable:
Purchase a well-known brand
of fuel.Install and regularly
service a good, visual-type fuel filter/water separator between
the fuel tank and the engine. The Raycor 500
MA or 230
RMAM are good examples of such filters.
ENGINE OIL
Use a heavy duty engine oil with an API classification of CF,
CG-4, CH-4 or CI-4. Change the engine oil and filter after an
initial 50 hours
of break-in operation. Then follow the oil and
filter change intervals as specified in the
MAINTENANCE
SCHEDULE in this manual. Westerbeke Corporation does
not approve or disapprove
of the use of synthetic oils. If
synthetic oils are used, engine break-in must be performed
using conventional oil. Oil change intervals must be as in the
MAINTENANCE SCHEDULE, not extended because
synthetic oils are used.
SAE OIL VISCOSITY GRADES
For all temperatures use SAE 1DW-40 or 15W-40.
OIL PRESSURE
The engine's oil pressure, during operation, is indicated
by the oil pressure gauge on the instrument panel. During
normal operation, the oil pressure will range between 35 and
65 psi 2.5 and 3.9 kg/cm2
).
NOTE: A newly started, cold engine can have an oil pressure
reading upwards of60 psi (4.2 kg/cm2 >. A warmed engine can
have an oil pressure reading as low as
25 psi (1.8 kg/cm2 >.
These readings will vary depending upon the temperature of
the engine, the loadplaced on the engine, and the RPM's.
ENGINE COOLANT
WESTERBEKE recommends a mixture of 50% antifreeze
and 50% distilled water. Distilled water is free from the
chemicals that can corrode internal engine surfaces.
The antifreeze performs double duty.
It allows the engine to
run at proper temperatures by transferring heat away from
the engine to the coolant, and lubricates and protects the
cooling circuit from rust and corrosion. Look for a good
quality antifreeze that contains Supplemental Cooling
Additives (SCAs) that keep the antifreeze chemically
balanced, crucial to long term protection.
The distilled water and antifreeze should be premixed before
being poured into the cooling circuit.
PURCHASING ANTIFREEZE
Rather than preparing the mixture, WESTERBEKE
recommends buying the premixed antifreeze so that so that
when adding coolant the mixture will always be correct.
There are two common types
of antifreeze, Ethylene Glycol
(green) and Propylene Glycol (red/purple), either can be used
but do not mix the two and if changing from one to another,
flush the engine thoroughly.
Premixed antifreeze for DIESEL Engines:
Specification #ASTM D53456.
MAINTENANCE
Change the engine coolant every five years regardless of the
number
of operating hours as the chemical additives that
protect and lubricate the engine have a limited life.

PREPARATIONS FOR INITIAL START ·UP
PRESTART INSPECTION
Before starting your generator for the first time or after a pro-
longed layoff, check the following items:
• Check the engine oil level: add oil to maintain the level at
the full mark on the dipstick.
• Check the fuel supply and examine the fuel filter/separator
bowls for contaminants.
• Check the DC electrical system. Inspect wire connections
and battery cable connections.
• Check the coolant level in both the plastic recovery tank ·
and at the manifold.
NOTE: After the initial running of the generator; the air in
the engine's cooling system will be purged to the coolant
recovery tank. Open the air bleed petcock to ensure that
the cooling system is purged of air. Aftershutdown and
after
the engine has cooled, the coolantfrom the recovery
tank will be drawn into the engine's cooling system to
replace the purged air.
Before subsequent operation of the generator; the engine's
manifold should
be topped off, and the coolant recovery
• Check load leads for conect connections as specified in
the wiring diagrams.
• Examine the air inlet and outlet for air flow obstructions.
• Be sure no other generator or utility power is connected to
the load lines.

• Be sure that in power systems with a neutral line that
the neutral is properly grounded (or ungrounded) as the
system requires, and that the generator neutral is properly
connected to the load neutral.
In single phase systems an
incomplete
or open neutral can supply the wrong line-to-
neutral voltage on unbalanced loads.
• Make certain the cooling water thru-hull petcock is open.
A CAUTION: When starting the generator, it is
recommended that all AC loads, especially large
motors, be switched OFF until the engine has come
up to speed and, in cold climates, starts to warm up.
This precaution will prevent damage caused by
unanticipated operation of the AC machinery and will
prevent a cold engine from stalling.

CAUTION: Repeated ctank cycles without a start can result
in the engine's exhaustsystem filling with raw water. This
raw water can enter the engine's cylinders
by way of the
exhaust manifold.
If after three crankcycles, the unit does
notstart, drain the system's muffler and investigate
and
correct the cause of no start. Engine damage, the result
of raw water entry, is not a warrantable issue.

GENERATOR BREAK-IN PROCEDURE
DESCRIPTION
Although your engine has experienced a minimum of one
hour
of test operations at the factory to make sure accurate
assembly procedures were followed and that the engine
· operated properly, a break-in time is required. The service
life
of your engine is dependent upon how the engine is
operated and serviced during its initial hours of use.
Breaking-in a new engine basically involves seating the
piston rings to the cylinder walls. Excessive oil consumption
and smoky operation indicate that the cylinder walls are
glazed or scored, which
is caused by overloading the
engine during the break-in period.
Your new engine requires approximately 50 hours
of initial
conditioning operation to break in each moving part in order
to maximize the performance and service life
of the engine.
Perform this conditioning carefully, keeping in mind the
following:
Start the engine according to the STARTING PROCEDURE
section. Run the engine while checking that all systems (raw
water pump, oil pressure, battery charging) are functioning.
AFTER START-UP
Once the generator has been started, check for proper opera-
tion and then encourage a fast warm-up. Run the generator
between 20% and 60%
of full-load for the first 10 hours.
After the first
10 hours of the generator's operation, the load
can be increased to the full-load rated output, then periodi-
cally vary the load.
Avoid overload at all times.
An overload is signaled by smoky
exhaust with reduced output voltage and frequency. Monitor
the current being drawn from the generator and keep it within
the generator's rating. Since the generator operates at 1800
rpm to produce 60 hertz (or at 1500 rpm to produce 50
Hertz), control
of the generator's break-in is governed by the
current drawn from the generator.
NOTE: Be aware of motor starting loads and the high current
draw required
for starting motors. This starting amperage
draw can be 3 to 5 times normal running amperage. See
GENERATOR INFORMATION in this manual.
GENERATOR ADJUSTMENTS
Once the generator has been placed in operation, there may be
governor adjustments required for engine speed (hertz) during
the engine's break-in period (first 50 hours) or after this
period see ENGINE SPEED (HERTZ) ADJUSTMENT) under
ENGINEADJUSTMENTS .. A no-load voltage adjustment
may also be required in conjunction with the engine's speed
adjustment see GENERATOR INFORMATION.
THE DAILY ROUTINE
CHECK LIST
Follow this check list each day before starting your generator.
• Check that all generator circuit breakers (power panel) are
in the off position before starting.
• Record the hourmeter reading in your log (engine hours
relate to the maintenance schedule.)
Any deficiency or problems in the following items must
be corrected before start up.
• Visually inspect the engine for fuel, oil, or water leaks.
• Check the oil level (dipstick).
• Check the coolant level in the coolant recovery tank.
• Check your fuel supply.
• Check the starting batteries (weekly).
• Check drive belts for wear and proper tension (weekly).
CHECK WITH THE ENGINE RUNNING.
• Check for abnormal noise such as knocking, vibrating and
blow-back sounds.
• Confirm exhaust smoke:
When the engine is cold
-White Smoke.
When the engine is warm -almost Smokeless.
When the engine
is overloaded -some Black Smoke.
NOTE: Some unstable running may occur in a cold engine.
This condition should abate as normal operating temperature
is reached
and loads are applied.
A CAUTION: Do not operate the generator for long
periods of time without a load being placed on the
generator.
STOPPING THE GENERATOR
Remove the AC amperage loads from the generator one at a time.
Allow the generator to run for 3-5 minutes to stabilize the operating
temperature. Then push the stop button. Once the generator shuts
down,
tum off the panel DC breaker as a safety precaution.

CAUTION (WESTERLINK or NMEA-2000): The electronic components in the
Digital Diesels draw a very small amount of amperage (milli-amps) from
the generator's starting battery when the unit is
in a static state. This
maybe as much as 50 milli-amps for the system ECU and 50 milli-amps
for each display. This can be as much as 72 amp-hours
in a months time
with no generator use. It is not necessary to be concerned with this slight
amperage draw during normal seasonal use. However,
if the generator
set is not
to be used for a number of months, such as winter storage, it is
best to disconnect the DC power to the generator with a NMEA-2000
system or shut
off the DC breaker on the generator's control box for a
WESTERLINK system.
NOTE: Keep in mind that the Westerbeke generator maybe the DC power
supply for the vessel's NMEA-2000 network.
