ENGINE LUBRICATING OIL
OIL GRADE
Use a heavy duty engine oil with an API classification of S1.
Change the engine oil after an initial 50 hours of break-in
operation, and every 100 hours of operation thereafter. For
recommended oil viscosity, see the following chart:
OperatIng Temperature 011 ViscDsity
Above 68' F (20' C) SAE 30, 10W-30 or 15W-40
41' - 68' F (5'_20' C) SAE 20 or 10W-30

CHANGING THE ENGINE OIL
The engine oil should be warm. Remove the oil drain hose
from its attachment bracket and lower it into a container and
allow the oil to drain, or attach a pump to the end of the drain
hose and pump the old oil out. Make sure the oil drain hose
is properly secured in its holder after all of the old oil has
been drained.
Always observe the old oil as it is removed. A yellow/gray
emulsion indicates the presence of water in the oil. Although
this condition is rare, it does require prompt attention to
prevent serious damage. Call a competent mechanic if water
is present
in
the oil. Raw water present in the oil can be the
result of a fault in the exhaust system attached to the engine
and/or.a siphoning through the water cooling circuit into the
exhaust, filling into the engine.

Replacing the Oil Filler
When removing the used oil filter, you may find it helpful to
punch a hole in the upper and lower portion of the old filter
to drain the oil into a container before removing it. This helps
to lessen spillage. An automotive filter wrench should be
helpful in removing the old oil filter. Place some paper towels
and a plastic bag around the filter when unscrewing it to catch
any oil that's in the filter. Inspect the old oil filter as it is
removed to make sure that the rubber sealing gasket comes
off with the old oil filter. If this rubber sealing gasket remains
sealed against the oil filter adapter, gently remove it. When
installing the new oil filter element, wipe the filter gasket's
sealing surface on the oil filter adapter free of oil and apply a
thin coat of clean engine oil to the rubber sealing gasket on
the oil filter. Screw the filter onto the threaded oil filter stub,
and tighten the filter finnly by hand.
NOTE:
Use genuine WESTERBEKE oil filters. Generic filters
are not recommended.
REFILLING THE OIL SUMP
Add fresh oil through the valve cover. After refilling the oil,
run the engine for a few moments while checking the engine's
oil pressure. Make sure there is no leakage around the new
oil filter or from the oil drain system, and then stop the
engine. Then check the quantity of oil with the lube oil
dipstick. Fill

OIL PRESSURE
CHANGING OIL FILTER
The engine's oil pressure, during operation. is indicated
by the oil'pressure gauge on the instrument Ranel. During
normal operation, the oil pressure will range between 40 and
60 psi (2.8 and 4.2 kg/em').
NDTE:
A newly started. cold engine can have an oil pressure
reading up to 60 psi (4.2 kg/em". A wanned engine can have
an oil pressure reading as low as 35 psi (2.5 kg/em". These
readings will vary depending upon the temperature of the
engine and the rpms. Refer to ENGINE ADJUSTMENT
pages for TESTING OIL PRESSURE.
