IMPORTANT
PRODUCT SOFTWARE DISCLAIMER
Product software of all kinds, such as brochur es, dr awing s,
technical data, operator's and workshop manuals, parts lists
and parts price lists (and other related information),
instruct ions and speci fica t ions prov ided from source s other
than Westerbeke, is not within Westerbeke's control and,
accordingly, is provided to Westerbeke customers only as a
courtesy and service. WESTERBEKE CANNOT BE RESPONSIBLE FOR
THE CONTENT OF SUCH SOFTWARE, MAKES NO WARRANTIES OR

SUCH SOFTWARE.
For example, components and sub-assemblies incorporated into
Westerbeke's products and supplied by others (such as engine
blocks, fuel systems and components, transmissions, electri-
cal components, pumps and other products) are generally sup-
ported by their manufacturers with their own software, and
Westerbeke m'ust depend on such software for the design of
Westerbeke's own product software. Such software, however,
may be outdated and no longer accurate. Routine changes made
by Wester beke' s supplier s, of wh ich Wester beke rarely has
notice in advance, are frequently not reflected in the
supplier's software until after such changes take place.
Westerbeke customers should also keep in mind the time span
between pr intings of Westerbeke product software, and the
unavoidable existence of earlier, non-current Westerbeke
software ed i t ions in the field. Addi t ionally, most
Westerbeke products include customer-requested special
fea tur es that fr equen tly do not include complete documen-
tation.
In summation, product software provided with Westerbeke pro-
ducts, whether from Westerbeke or other suppliers, must not
and cannot be relied upon exclusively as the definitive
authority on the respective product. It not only makes good
sense, but is imperative that appropriate representatives of
Westerbeke or the supplier in question be consulted to deter-
mine the accuracy and currency of the product software being
consulted by the customer.

GENERAL
Introduction
This manual contains the equipment operating procedures as well as
information to assist the operator to maintain the equipment in proper
working order. Study and follow the instructions carefully. A
planned rna in tenance prog r am is included in th is manual; adher ing to
the prog ram will result in better equipment per formance and longer
equipment life. Proper diagnosis of a problem is the most important
step to satisfactory repair; consequently, a troubleshooting table is
included.
Understanding the Gasoline Powered Generator
The gasoline engine driving the AC generator is in many ways similar
to an automobile engine. The cylinders are vertical and in-line, with
a belt-driven, overhead camshaft. The engine utilizes a breaker
points and condenser type distributor which is horizontally-mounted
and camshaft-driven, a pressure type lubrication system, and a
thermostatically-controlled water-cooled engine block with an ex-
changer system.
To a great extent, the gasoline engine used to drive the AC generator
~equires the same preventive maintenance that any responsible operator
would give the gasoline engine in his automobile. The most important
factors contributing to the long life of the unit are proper ven-
tilation and maintenance of the fuel system, ignition system, cooling
system, and the generator end.
Order ing Parts
When contacting your Westerbeke dealer, parts distributor, or the fac-
tory about your Westerbeke unit, always provide the model number and
serial number as they appear on the nameplate (located on the surface
of the exhaust manifold/coolant tank). This information is necessary
in order to identify your unit.
Note that component locations in the manual are referenced from the
front of the engine which is the pulley/drive belt end. (The
flywheel/generator or transmission end is the rear end.) Left and
right sides are determined by the engine; imagine straddling the
eng ine and facing in the same dir ection as the front of the eng ine:
the left side is at your left, the right side at your right.
Westerbeke engines and generator sets are thoroughly checked and given
a final run under various load conditions before leaving the factory.
This is done to ensure dependable operation, long service, and a
satisfied owner. A record of this test is maintained at the factory.
Care at the factory during assembly, and thorough testing, have
resulted in a Westerbeke gasoline engine-driven generator capable of
many thousands of hours of dependable service. However, the manufac-
turer cannot control the treatment the unit receives in the field.
That part is up to the owner/operator.

INSTALLATION
General
Proper location and installation of the generator set in the vessel
are of prime importance.
Factor s in the installation that must be considered are ventilation
for the generator for proper cooling and engine combustion air;
exhaust system to properly discharge raw cooling water, quiet the
exhaust and expel exhaust gas; cooling water supply; fuel supply;
and electrical connections.
Factors in the location that must be considered are proper support
and access for serv icing and repair s. These factor s will be dis-
cussed in this manual.
(1/2" Mounting Holes)
There are four 1/2-inch bolt holes in each generator mounting rail to
properly secure the generator to its mounting platform.
Location
The location should be such that it is ..9!..,y, above low-lying vapor
areas, and away from being splashed by bilge water or water from above.
It should be properly ventilated and accessible for minor servicing
and repairs. Access for major repairs should be given consideration
as well. The location must be properly ventilated to provide the
fresh cooling air for the generator end and for engine combustion.
Hot generator discharge air must be removed from the generator area.
The platform on which the generator is mounted should be strong enough
to support the generator and securely hold the mounting rails
fastened to it at all angles of vessel operation.
7

ventilation
The generator set needs fresh cool air for combustion within the
engine cylinders, for generator cooling and to remove harmful or flam-
mable gasoline fumes from around the generator set. The 9 KW BTG en-
gine requires air flow of 32 cubic feet per minute (0.906 cubic meters
per minute) and the generator end requires from 225 to 250 cubic feet
per minute (6.37 to 7.08 cubic meters per minute) air flow.
NOTE: Heated generator discharge air should not be allowed
to accumulate in the generator compartment. It should be
removed to prevent recirculation through the generator.
Exhaust System
WARNING
Exhaust gas is deadlY1 the exhaust system must be tight and
free of leaks.
All exhaust systems must be configured to prevent the entry of water
into the engine exhaust manifold and cylinders while the vessel is
under power or sail, heeling, from following seas, when backing down
or any other conditions.
General tips on exhaust system:
• Dry portions of exhaust system, between the engine and cooling
water injection point, must be properly insulated.
• The exhaust hose must be of adequate size and minimal run to help
prevent excessive back pressure. The use of fittings and elbows
should be limited as these create back pressure.
• The gener ator exhaust system ~ be separate from any other
engine exhaust system.
• Dry stack type exhaust systems ~ be flexibly attached to the
engine manifold, be properly supported, have a spark arrestor and
be protected against water entry.
• Hydro hush mufflers should be mounted as close to the generator as
possible and the exhaust/cooling water mixture from the exhaust/
water injected elbow should drop down into the muffler.
•
units installed with exhaust manifolds close to or below
vessel water line must have anti-siphon protection in the
water plumbing to the exhaust/water injected elbow.

CAUTION
Overcranking with no engine start results in excessive
amounts of cooling water pumped in to the exhaust system.
Exhaust gas pressure may not always be sufficient to
discharge accumulated water during periods of excessive
cranking. Shut off thru-hull water supply until unit starts
and then open once started. Investigate reason (s) for hard
starting and correct.
Fuel System
WARNING
Gasoline leakage in or around the generator compartment is a
potential cause of fire and/or explosion. Repair leaks
promptly and ensure the compartment is properly ventilated.
The fuel supply to the generator should be from its own pickup in the
tank and not teed off the supply to another engine.
Anti-Siphon Protection is the term applied to the means of preventing
siphoning action that permits fuel to continue to flow out of the fuel
tank when there is a break or rupture in the fuel supply line, or when
a fitting loosens to create a leak in the line between the fuel tank
connection and the connection to the engine. Fuel systems must be
designed and installed to protect against fuel siphoning. ----
The illustrations shown on the following page (taken from Coast Guard
publication Fuel System Compliance Guideline), show basic fuel system
layouts with anti-siphon protection.
NOTE: Anti-siphon devices or electrically-operated fuel
shut-off valves must be installed when the fuel distribution
line is routed below the top level of the fuel tank.
The fuel line should be routed and supported to prevent leaks from
vibration and chafing. The line should be supported every 12 - 14
inches. Use as few connections in the supply line as possible.
A filter/water separator is recommended for use in the fuel system,
between the fuel tank and eng ine, to remove harmful debr is and
water from the fuel, both of which are prime causes of fuel system
and/or engine failure.
The fuel tank vent should be routed, and the discharge located, so that
that water cannot enter the fuel tank (s) through the vent. Moisture
must not be allowed to accumulate in the vent line.

Fuel system components must be compatible with oxygenate (butanes,
alcohols) blended fuels.--pailure to ensure compatibility will result
in the component failure and possible injury to the user.
The use of check valves in place of the solenoid-type shut-off valves
is discouraged. Check valves may tax the ability of the fuel lift
pump on the eng ine to draw fuel through them. Also, they can trap
debris under their seats, defeating their purpose. Too high a crack-
ing pressure for check valves will contribute to vapor lock shutdowns.
Cooling System
The generator engine is fresh water-cooled by an engine-mounted heat
exchanger. Sea water is used as the exchange cooling medium and is
pumped into the exchanger by a sea water pump and then injected into
the exhaust discharge, carrying with it the heat removed from the
engine fresh water system.
The sea water pump is belt-driven
and sea water should be supplied to
it through a flush-type hull fit-
ting. This sea water should be
brought through a visual-type sea
water strainer and then delivered to
the pump. Hoses routed from the
thru-hull fitting to the strainer
and to the sea water pump, should
be wire-reinforced to prevent
collapse from the suction of the sea
water pump during generator opera-
tion. Sea water strainers should be
mounted at or below the water line
so as to be always self-primed.
CAUTION
Do not use a scoop-type thru-
hull fitting for the sea water
supply to the generator. Water
pressure against this type
fitting, while the vessel is
underway, can push water past
the sea water pump impeller and in to

the generator exhaust system, filling it and the engine as well.
Flush-type, clear, thru-hull fittings are recommended and should
be located on the hull so as to be below the waterline during all
angles of boat operation.
The use of common-type street elbows is not recommended for
plumbing the sea water circuit. These generally have a very
restrictive inside diameter. Machined fittings are preferred.
12

Automatic Shutdown
High Exhaust Temperature Shutdown Switch (normally closed)
An exhaust temperature switch is located on the exhaust elbow and will
open the ignition circuit should the switch sense excessive tem-
perature, indicating a lack of proper sea water coolant flow. This
switch opens at 260 - 270·F (127 - l32·C) and resets at approximately
22S·F (107·C).
High Water Temperature Shutdown Switch (normally closed)
A high water temperature switch is located in the area of the thermo-
stat housing to sense fresh water coolant temperature and shut down
the generator should the engine fresh water coolant operating tempera-
ture reach approximately 20S· F (96·C) + S·. This switch resets at
19S·F (approximate). -
Low Oil Pressure Shutdown Switch (normally open)
A low oil pressure shutdown switch is located in the engine oil
gallery and is closed when eng ine oil pressure reaches 10 - IS psi,
maintaining the electr ical run circuit. This switch will open and
shut the generator down when engine oil pressure drops to 10 - IS psi.
Exhaust Back-Pressure
Exhaust back-pressure should be checked
prior to putting a generator into ser-
vice. (Refer to the illustration.) Ex-
cessive back-pressure will affect engine
performance and generator power output.
Measure back-pressure at the exhaust
elbow with generator under full load.
Back-pressure (manometer) should not be
over 3 inches of mercury (0.104 kg/cm
2
),
39 inches of water column (0.099) kg/cm
2
at 4· C}, 22 ounces per square inch or
1-1/2 psi (967 kg/m
2
).
Excessive back-pressure can be
by small diameter exhaust hose,
muffler, sharp bends, fittings,
pockets or high volume of water
exhaust system.

An oil sump drain hose is installed on the engine with the discharge
end secured by a bracket at the front of the engine. Oil may be
drained from this hose by removing the cap and the discharge end of
the hose from the suppor t br acket and lower ing the hose in to a con-
tainer. The hose cap fitting is 1/4-NPT and can be extended, or a
pump
added, for easier removal of oil, if desired.
13

DC Electrical Connections
A common ground for negative (-) DC is found at the bellhousing of the
generator, next to the starter, in the form of a threaded grounding
stud. It is recommended that the battery ground be connected here.
Connect battery positive (+) to the starter solenoid terminal tagged
for this connection.
CAUTION
To avoid an overcharg ing condition, and poss ible equipment
failure, do not disconnect the DC battery source while the
engine is running.
Grounding
The generator set must be grounded to comply with United States Coast
Guard regulation 33CFR-183 which specifies that a common conductor be
connected between the generator set and the vessel's main propulsion
engine grounded starter motor circuit. This conductor (common ground)
prevents accidental passage of cranking current through fuel systems
and smaller electrical conductors common to the engines. This conduc-
tor must be the same size as the largest battery cable.
Optional Remote Start/Stop Panel and Instrument Panel
An optional remote start/stop panel is available, on which are mounted
switches and a green RUN indicator light. This RUN indicator light
will glow when the ON switch is depressed, dim when the START switch
is depressed to engage the starter, and then glow br ight when the
engine starts (a signal to release the START switch). This panel is
connected to the terminal blocks in the generator-mounted control
panel. (Refer to wir ing diagrams * 35706 and * 36397.) This remote
start/stop panel can be mounted in areas such as the wheel house or
galley.
An optional instrument panel is available which is supplied with
an engine oil pressure gauge, water temperature gauge, DC voltmeter,
engine operating hourmeter and start/stop control switches. This panel
can be wired to the terminal blocks in the generator-mounted control
panel and mounted at the location where the instruments can be moni-
tored and the switches operated. (Refer to the DC wir ing schematics
* 35698 and * 36397 for proper connection poin ts and recommended wir e
sizes for specific wire lengths.)
