1.
Draining the Oil Sump
Remove the oil drain hose from its attachment brack-
et 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 yel-
low/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 should water be present in the
oil. Sea 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 sea water cooling cir-
cuit
into the exhaust, filling it up into the engine (refer
to
the installation illustrations on page 26).
2.
Replacement of the Oil Filter
When removing the used oil filter, you may find it help-
ful 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 style automotive filter
wrench
should be helpful in removing the old oil filter. Place
some paper towels and a plastic bag around the fil-
ter
when unscrewing it
to
catch
any
oil left in the fil-
ter.
(Oil
or
any
other fluid on the engine reduces the
engine's cooling ability.
Please keep
your
engine
clean.)
Inspect the old oil filter as it is removed
to
make sure that the rubber sealing gasket came off
with the old oil filter.
If this rubber sealing gasket
remains sealed against the engine block, gently
remove
it.
The replaceable cartridge-type oil filter re-
quires
no
cleaning inside, so it may be properly dis-
posed of.
When installing the
new
oil filter element, wipe the filter gasket's sealing surface on the engine
block
free of
oil and
apply
a thin coat of clean engine oil
to
the rubber gasket
on
the oil filter. Screw the filter
onto
the
threaded oil filter stub, and then tighten the filter firmly
by
hand.
NOTE: Generic filters are not recommended, as the material standards
or
diameters of im-
portant items on generic parts might be entirely different from genuine parts.
Immediately after
an oil filter change and oil fill, run the engine
to
make sure the oil pressure is normal and that
there are
no
oil leaks around the new oil filter.
