CALIFORNIA PROPOSITION 65 WARNING Marine diesel and gasoline engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. A WARNING: Exhaust gasses contain Carbon Monoxide, an odorless and colorless gas. Carbon Monoxide is poisonous and can cause unconsciousness and death.
SAFETY INSTRUCTIONS INTRODUCTION PREVENT BURNS - FIRE Read this safety manual carefully. Most accidents are caused by failure to follow fundamental rules and precautions. Know when dangerous conditions exist and take the necessary precautions to protect yourself, your personnel, and your machinery. The following safety instructions are in compliance with the American Boat and Yacht Council (ABYC) standards.
SAFETY INSTRUCTIONS ACCIDENTAL STARTING A WARNING: Carbon monoxide (CO) is a deadly gas! A WARNING: Accidental starting can cause injury or death! • To prevent accidental starting when servicing the generator, remove the 8 amp fuse from the control panel. • 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.
SAFETY INSTRUCTIONS ABYC, NFPA AND USCG PUBLICATIONS FOR INSTALLING DIESEL ENGINES • 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 belt's tension while the engine is operating.
CARBON MONOXIDE "CO"I LOW-CO· GENERATORS IMPORTANT INFORMATION DESCRIPTION In a closed space, such as the engine compartment, the boat, or underneath a stem swim platform, concentrations will potentially rise to the undiluted level emanating from the exhaust system due to a lack of fresh air to dilute the exhaust gas. Therefore, one should never rely on dilution of the exhaust to provide a margin of safety. Carbon monoxide "CO" is a component of engine exhaust.
EMISSIONS This genset meets the requirements of California's Exhaust Emissions Standards as stated on the nameplate. You should carefully review operator (Owner) Installation and other manuals and information you receive with your genset. If you are unsure that the installation, use, maintenance or service of your genset is authorized, you should seek assistance from an approved WESTERBEKE dealer.
CARBON MONOXIDE "CO"I LOW-CO GENERATORS IMPORTANT INFORMATION Whenever taking the time to verify proper co levels from the exhaust with a co analyzer, always take theopportunity to use the analyzer to "sniff' around the engine looking for CO from exhaust leaks. Pay close attention to the connection of the cylinder block to the sump plate, the sump plated to the water injected exhaust elbow casting and all subsequent downstream exhaust components and hoses and connection points.
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.

INSTALLATION SIDE VIEW RIGGING AND LIFTING The engine/generator is fitted with lifting eyes. Attach wire rope or chain slings capable of supporting the engine/generators weight to the eyes and lift the engine/generator by means of tackle attached to these slings. The lifting eyes have been designed to carry the full weight: auxiliary slings are not necessary. NOTE: Rigging work is best done by someone experienced and competent in handling machinery.
INSTALLATION/EXHAUST SYSTEM RAW WATER DISCHARGE When the generators location is above the loaded water line of the vessel during all attitudes of vessel operation, it is still advisable to loop the raw water discharge hose at least 6 • inches or more above the generator and then down to the inlet connection on the water injected exhaust elbow. The fresh water that flows thru the engine is cooled by a continuous flow of raw water (via the heat exchanger).
FUEL, ENGINE OIL AND ENGINE COOLANT GASOLINE ENGINE COOLANT Use only unleaded gasoline with an octane rating of 89 or higher. Higher octane is recommended. The use of lower octane gasoline will adversly affect engine performance. Ethanol blends must not exceed E-lO. When fueling, follow U.S. Coats Guard Regulations. Close all hatches and companionways to prevent fumes from entering the vessel. Ventilate properly after fueling and before starting the generator or main engines.
CONTROL PANEL • START/STOP PANEL DESCRIPTION FAILURE TO START To Start: Press the rocker switch to the start position and The start cycle will automatically terminate if the engine fails to start after 8 seconds of cranking.

When servicing/replacing DC components, turn off the 20 amp DC circuit breaker on the control panel, or disconnect the battery terminals. SCHEDULED MAINTENANCE EXPLANATION OF SCHEDULED MAINTENANCE I DAilY CHECK BEFORE START-UP Coolant Level Check at recovery tank, if empty, check at manifold.
MAINTENANCE SCHEDULE SCHEDULED MAINTENANCE EXPLANATION OF SCHEDULED MAINTENANCE EVERY 250 OPERATING HOURS OR YEARLY (cant.) 'Exhaust CO Level Sample exhaust with CO analyzer. ·Exhaust Elbow Test exhaust elbow for structural integrity. Replace if elbow is corroded or deteriorated. Always use a new gasket. NOTE: A leaking exhaust elbow or gasket can cause carbon monoxide exposure! Exhaust System Carefully inspect for leaks. Check anti-siphon valve operation.
ENGINE LUBRICATING OIL DESCRIPTION Use a heavy duty engine oil with an API classification of SJ, SL, or SM. Change the engine oil and filter after an initial 50 hours of break-in operation. Then follow the oil change ' interval as specified in the MAINTENANCE SCHEDULE in this manual. An oil viscosity of SAE-15W-40 is recommended for this engine in all conditions, and all seasons. Westerbeke Corporation does not approve or disapprove the use of synthetic oils.
FUEL SYSTEM GASOLINE ENGINE FUEL FILTER Use only unleaded gasoline with an octane rating of 89 or higher. Higher octane is recommended. The use of lower octane gasoline will affect engine performance adversely. Ethanol blend must not exceed E 1o. Periodically check the fuel connections and the bowl for leakage. Replace the filter element after the first 50 hours then follow the MAINTENANCE SCHEDULE.
COOLING SYSTEM FRESH WATER COOLING CIRCUIT Fresh water (antifreeze) is moved through the engine by a belt driven circulating pump, absorbing heat from the engine. Some of the coolant by-passes the thermostat to maintain circulation in the engine and is drawn through the heat exchanger. The engine operating temperature rises and the thermostat reacts to this and starts to open allowing more coolant to flow through the heat exchanger.
COOLING SYSTEM TO WATER COOLED EXHAUST THERMOSTAT A thennostat, located in the coolant filler cap housing (illustrated below), controls the coolant's temperature by allowing more or less coolant through it to the engine's heat exchanger. When the engine is first started, the closed thennostat prevents coolant from flowing through it to the heat exchanger. Some coolant is by-passed via a by-pass hose on the sump plate to the exchanger.
COOLING SYSTEM I WATER PUMPS DESCRIPTION CHANGING THE WATER PUMP IMPELLERS The fresh water cooling system has the raw water pump mounted above the fresh water (coolant) pump as illustrated. These pumps are self-priming, rotary pumps, with non-ferrous housings and Neoprene impellers. The impellers have flexible blades that wipe against a curved cam plate within the impeller housing, producing the pumping action. These pumps can not be allowed to run dry.
DC CIRCUIT/BATTERY DESCRIPTION Testing the Circuit The DC Circuit functions to start, operate and stop the generator's engine. The circuit is best understood by reviewing the DC Wiring Diagram and Wiring Schematic. The engine's DC wiring is designed with three simple basic circuits: start, run, and stop. If the battery is not charging, check the fuse. To test the circuit, remove the fuse and test with a voltmeter between the fuse holder connection and ground.
ENGINE COMPONENTS: SPARK PLUGS The spark plugs should be cleaned and re-gapped after the first 50 hour break-in period, then inspected every 250 hours thereafter and replaced as needed. AIR SCREEN A WARNING: Do not remove the spark plugs while the engine is hot. Allow the engine to cool before removing them. SPARK PLUG GAP: 0.032 - 0.035io. (0.8 - 0.9mm). SPARK PLUG TORQUE: 11 -15Ib-ft (15 - 26 Nm).
ENGINE ADJUSTMENTS ADJUSTING THE DRIVE BELT BELT ASSEMBLY (viewed from underneath) The engine's drive belt is located under the engine. To access the belt, for inspection and/or adjustment, remove the cover as shown. Inspect the belt for wear along the edges and for proper belt tension (belt should be tight).
