Care Of The Fuel Supply
Use only clean properly filtered fuel! The clearance of some
components in the unit's fuel system are very critical; 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
is
clean and pure, the following practice is
advisable:
Purchase a well-known brand of fuel.
Install and regularly service a good, Coast Guard approved
metal bowl type filter/water separator
between
the fuel tank
and the engine.
ENGINE OIL
Use a good brand of engine oil with an API and SAE
designations as listed in the SPECIF1CATION Section of
this manual.
Change the engine oil and filter after an initial 50 hours of
engine 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
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 listed in the MAINTENANCE
SCHEDULE section in this manual and not to be extended
if synthetic oils are used.
NOTE:
The information above supercedes all previous
statements regarding synthetic oil usage.

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 It also lubricates and prote.cts the
cooling circuit from rust and corrosion. Look for a good
quality antifreCze 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.
NOTE: Look for the new environmentally-friendly long lasting
antifreeze that is now available.
A proper 50/50 mixture as recommended will protect the
engine coolant temperature to temperatures of -40°F.
COOLANT RECOVERY TJ\NK
A coolant recovery tank kit is supplied with each generator.
The pwpose of this recovery tank is
to
allow for engine
coolant expansion and contraction during engine. operation,
without the loss of coolant and without introducing air into
the cooling system.

NOTE: This tank, with its short run of plastic hose, is best
located at or above the level of the engines exhaust
manifold.
