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 obser:ve the old oil as it is removed. A yellow/gray
emulsimi indicates the presence of water in the oil. Although
this condition is rare, it does require prompt attention to
prevent selious 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 raw water cooling
circuit into the exhaust, filling into the engine.
NOTE:
Be very careful not to overfill the oil sump. Overfilling
ofthe oil sump will result in erratic operation of the engine,
white-smokey/oil laden exhaust discharge, possible ham
starting or no star( and fouled spark plugs.

contaminants. Avoid prolonged skin contact. Clean skin
and nails thoroughly using soap and water. Launder or
discard clothing or rags containing used oil. Discard

Replacing the Oil Filter
Whe~ 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 fmnly 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 Rressure .. Make sure there is no leakage around the new
oil filter or from the oil drain system, and then stop the
engine. Then cheek the quantity pf oil with the lube oil
dipstick: Fill to, but not over, the FULL mark on the dipstick.
