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
itlast.
• 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.
BAnERY EXPLOSION
A WARNING: Batteryexplosion can cause injury
or death!
• Do not smoke orallow 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 off all electrical
equipment in the vicinity to prevent electrical arcing dur-
ing servicing.
• Never connect the negative (-) battery cable to the posi-
tive (+) connection terminal ofthe 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
accmnulation ofexplosive 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.
BAnERYACID
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 protec-
tion. 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.
TOXIC EXHAUST GASES
A WARNING: Carlion 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
are securely attached and no warping exists. Pay close
attention to the manifold, water injection elbow, and
exhaust pipe nipple.
• Be sure the unit and its surroundings are well ventilated.
• In addition to routine inspection ofthe exhaust system,
install a carbon monoxide detector. Consult your boat
builder or dealer for installation ofapproved detectors.
• For additional information refer to ABYC T-22 (educa-
tional 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 sys-
tems. Exhaust sulfur causes rapid deterioration ofcopper
tubing resulting in exhauslfwater 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 symp-
toms or signs ofcarbon monoxide inhalation or poisoning
are:
Vomiting Muscular twitching
Dizziness Intense headache
Throbbing in temples 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 situa-
tion arises in which it is absolutely necessary to make
operating adjustments, use extreme care to avoid touch-
ing moving parts and hot exhaust system components.

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 belbw the Ibad waterline will result in
raw water damage to the engine and possibleflooding 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 valious 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 maline use. The system must be desigued to
prevent water from entering the exhaust under any sea conditions and at any angle
ofthe vessels hull.
A detailed Marine Installation Manual covering gaSOline and diesel,
engines and generators, is supplied with each unit. A pdf is available

INTRODUCTION
SERIAL NUMBER LOCATION
The engine's model number and serial number are located on
a nameplate mounted on the side of the engine's manifold.
The engine's serial number can also be found stamped into
the engine block on the flat surface of the block just forward
of the number one cylinders injection pump. Take the time to
enter this information on the illustration of the nameplate
shown below, as this will provide a quick reference when
seeking techuical information and/or ordering repair parts.
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 the
same general type as 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 mainte-
nance ofthe fuel, lubricating and cooling systems. Fuel and
lubricating filter elements must be replaced at the time
periods specified, and frequent checking for contaminant's
(water, sediment, etc.) in the fuel system is also essential.
Another important factor is the consistent use of the same
brand ofhigh detergent
diesel lubrication oil designed
specifically for diesel engines.
The diesel engine does differ from the gasoline engine,
however, in its method ofhandling and frring of fuel. The
carburetor and iguition systems are replaced by a single
component -the fuel injection pump - which performs the
function ofboth.
ORDERING PARTS
Whenever replacement parts are needed, always provide the
engine
model number and serial number as they appear on
the silver and black nameplate located on the manifold. You
must provide us with this information so we may properly
identify your engine. In addition, include a complete part
description and part number for each part needed (see the
separately furnished Parts List). Insist upon WESTERBEKE
packaged parts because will fit 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 engine. Your local WESTERBEKE dealer
will assist you in preparing an inventory ofspare parts.
See the SPARE PARTS page in this manual. For engine
accessories, see WESTERBEKE'S ACCESSORIESbrochure.
RAW WATER COOLING SYSTEM
Siphon-Break
For installations where the water injected exhaust elbow is
close to or will be below the vessels waterline, provisions
must be made to install a siphon-break in the raw water
supply hose to the water injected exhaust elbow. The siphon-
break provides an air vent in the raw water cooling system to
prevent raw water from filling the exhaust system and the
engine's cylinders when the engine is shutdown.
A CAUTION: 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 ofthe water-
injected exhaust elbow relative to the vessels waterline under
the vessels various operating conditions, install a siphon-
break. This precaution is necessary to protect your engine.
The siphon-break must be installed in the highest point of a
hose that is looped a miuimum of 20 inches (51cm) above
the vessels waterline. This siphon-break must always be
above the waterline during all angles ofvessel operation to
prevent siphouing.
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 manufacturerfor proper
maintenance.

DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
DIESEL FUEL
Use a diesel fuel that meets the requirements of No. 2-D
SAE J 3 [3 and has a Cetane rating of #45 or higher grade of
diesel
fuel according to ASTM D975
Care Of The Fuel Supply
Use only clean diesel fuel! The clearance of the components
in your engines fuel injection pump is very critical; invisible
dirt particles which might pass through the primary and sec-
ondmy filters can damage these finely machined 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 ensure that the fuel going into
the tank
for your engine's daily use is clean and pure, the
following
practice is advisable:
Purchase a well-known brand of fuel. The use of additives
to combat BACTERIAL growth in the fuel tank is
recommended such as Bio-Bor and an additive such as
Diesel Kleen +Centane Boost to help restore lubricity back
into
the diesel fuel when an Ultra Low Sulfur diesel is being
used.
Install
and regularly service a good, visual-type fuel
filtedwater separator between the fuel tank and the engine.
The Raycor
500 MA or 230 RMAM are good examples of
such
filters. A 10 micron filter element is recommended.
ENGINE OIL
Use a heavy duty diesel oil with an API classification of CF,

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 aHows the engine to
nm 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 chemicalJy
balanced, crucial
to long term protection.
The distilled water and antifreeze should be premixed before
being poured into the cooling circuit.
NDTE: Lookfor the new environmentally-friendly long lasting
antifreeze that is now available.
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 thorougbly.
Premixed antifreeze for DIESELEngines:
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 alimited life.
COOLANT RECOVERY TANK
The coolant recovery tank aIJows for the expansion and
contraction of the engines coolant during engine operation
without introducing
air into the system. This recovery tank is
provided with fresh water cooled models and with the fresh
water coolant conversion kit and must be installed before
operating
the engine.

PREPARATIONS FOR INITIAL START-UP
PRESTART INSPECTION
Before starting your engine for the first time or after a
prolonged
layoff, check the following items:
D Check the engine oil level. Add oil to maintain the level
at the high mark on the dipstick.
D Thrn on the fuel supply, then check the fuel supply and
examine the fuel filter/water separator bowl for
contaminants.
D Check the transmission fluid level.

ENGINE BREAK-IN PROCEDURE
DESCRIPTION
Although your engine has experienced a minimum of one
hour oftest operations at the factory to make sure accurate
assembly procedures were followed and that the engine oper-
ated 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 50 hours of use.
Breaking-in a new engine basically involves seating the pis-
ton rings to the cylinder walls. Excessive oil consumption
and smoky operation indicate that the cylinder walls are
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 fol-
lowing:
1. Start the engine according to the STARTING PROCE-
DURE section. Run the engine at fast idle while checking
that
all systems (raw water pump, oil pressure, battery
charging) are functioning.
2. Allow the engine to warm up (preferably by running at
fast idle)
until the water temperature gauge moves into
the 130 -140'P (55 -60'C) range.
3. While using the vessel, run the engine at various engine
speeds for the first 25 hours. Avoid prolonged periods of
idling.
4. Avoid rapid acceleration, especially with a cold engine.
5. Use caution not to overload the engine. The presence ofa
grey or black exhaust and the inability ofthe engine to
reach its full rated speed are signs of an overload.
,6. During the next 25 hours, the engine may be operated at
varying engine speeds, with short runs at full rated rpm.
Avoid prolonged idling during this break-in period.
CHECKLIST
o Monitor the control panel gauges.
o. Check for leaks of fuel and engine oil.
o Check for abnormal noise such as knocking, friction,
vibration and blow-back sounds.
o 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 and soot.
NOTE: See the TRANSMISSION section of this manualfor
break-in information on your transmission.
