1. Draining
the
OU
Sump. Discharge the used oil through
the sump drain hose (attached to the front
of
the engine)
while the engine is
warm. Drain the used oil completely,
replace the hose in its bracket, and replace the end cap
securely.

Always observe the used 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 quali-
fied mechanic should water be 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
of
raw water through the raw water cooling circuit into
the exhaust, filling the engine. This problem
is
often
caused by the absence
of
an anti-siphon valve, its poor
location
or
lack
of
maintenance.
2.
Replacing the Oil Filter. When removing the used oil
fil-
ter, you may find it helpful and cleaner to punch a hole
in
the upper and lower portion
of
the old filter to drain the
oil from it into a container before removing
it.
'This
helps
to lessen spillage. A small automotive filter wrench
should be helpful in removing the old oil filter.
NOTE:
Do
not punch this hole without first
loosening
the
filter
to
make
certain it
can
be
removed.
Place some paper towels and a plastic bag around the
fil-
ter when unscrewing it to catch any oil left in the filter.
(Oil or any other fluid on the engine reduces the engine's
cooling ability. Keep your engine clean.) 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 rub-
ber sealing gasket remains sealed against the filter
bracket, gently remove it.

3. Filling the Oil
Sump.
Add new oil through the oil filler
cap on the top
of
the engine or through the side oil
fill.
After refilling, run the engine for a few moments while
checking the oil pressure. Make sure there
is
no leakage
around the new oil filter or from the oil drain system, and
stop the engine. Then check the quantity
of
oil with the
lube oil dipstick. Fill to, but not over the high mark on
the dipstick, should the engine require additional oil.
