ENGINE OIL CHANGE
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 andlor a siphoning through the raw water cooling
circuit into the exhaust, tilling into the engine.

WARNING:
Used engine oil contains harmful
contaminants. Avoid prolonged skin contact. Clean skin
and nails thoroughly using soap and water. Launder or
discard clothing or rags containing used oil. Discard
used oil properly.
REPLACING THE OIL FILTER
When removing the used oil tilter, you may tind it helpful to
punch a hole in the upper and lower portion of the old tilter
to drain the oil into a container before removing it. TIlis helps
to lessen spillage. An automotive tilter wrench should be
helpful in removing the old oil tilter. Place some paper towels
and a plastic bag around the tilter when unscrewing it to catch
any oil that's in the tilter. Inspect the old oil tilter 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 tilter adapter, gently remove it. When
installing the new oil tilter element, wipe the tilter gasket's
sealing surface on the oil tilter adapter free of oil and apply a
thin coat of clean engine oil to the rubber sealing gasket on
the oil tilter. Screw the tilter onto the threaded oil filter stub,
and tighten the tilter tinnly 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 retilling 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 tilter or trom the oil drain system, and then stop the
engine. Then check the quantity of oil with the lube oil
dipstick. Fill to, but not over, the FULL mark on the dipstick.
