OIL
GRADE
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
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. SAE 15W-40 is suitable for use in
all seasons.
NOTE:
The information above supersedes all previous
statements regarding synthetic oil usage.
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
Filter
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
se~ling
surface on the oil filter adapter free
of
oil and apply a
thm
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 firmly 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

OIL
FILTER
The engine's oil pressure, during operation, is indicated
by the oil pressure gauge on the instrument
panel. During
normal operation, the
oi:l
pressure will range between
40
and
60 psi (2.8 and 4.2 kg/cm
2
).
NOTE:
A newly started, cold engine can have an oil pressure
reading up to
60 psi ( 4.2 kg/cm
2
).
A warmed engine can have
an oil pressure reading as low as
35
psi (2.5 kg/cm
2
). These
readings will vary depending upon the temperature
of
the
engine
and
the rpms. Refer to ENGINE ADJUSTMENT
pages
for
TESTING OIL PRESSURE.
