The oil filter is a disposable spin-on type. An oil filter
wrench can be used to remove the filter, but do not use
it
to
install the new filter. Overtightening the filter may cause it
to leak.
The installed angle of the engine affects oil lcvcl in the
cran kcase. To assure that the oil is drained and replaced
properly, perform the following procedure with the boat at
rest in the water.
1. Start the engine and wann
it
to normal operating tem-
perature under load, then shut
it
off.
2. Remove the d ipstick and wipe it clean with a lint-free
cloth or paper towel.
3. Insert the oil drain pump hose into the dipstick tube as
far as it
wiII
go .
4. Insert the other pump hose into a sealable container
large enough to hold the oil from the crankcase. Refer to
Table 3 to determine the capacity ofthe engine crankcase.
5. Operate the pump until it has removed all of the oi l
possible from the crankcase. Remove the pump hose from
the dipstick tube.
6. Place a drain pan or other suitable container under the
filter (F igure 5) to catch any oil spillage when the filter is
removed .
7. Unscrew the filter counterclockwise. Use the filter
wrench if the filter is tight.
8. Wipe the gas ket surface on the engine block clean with
a paper towel.
9. Coat the neoprene gasket on the new filter with a thin
coat of clean engine oii.
10. Screw the new filter onto the engine by hand until the
gasket just touches the engine block. At this point, there
will be a very slight resistance when turning the filter.
I I . Tighten the filter another 2/3 tum by hand. Using a
filter wrench can lead to overtightening the filter. This can
damage the filter or cause an oil leak .
12. Remove the oil filler cap or plug from the rocker arm
cover. See Figu re 2 (single cylinder models) or Figure 3
(multicylinder models) .
13. Reinstall the dipstick in the di pstick tube .
14. Refer to Table 3 to de termine the crankcase capacity
of the engine. Pour the specified amount of oil into the
rocker am cover opening and install the oil filler cap or
plug. Wipe up any spills on the cover.
CHAPTER THREE
NOTE
Check the area under and around the oiljil-
ter for leaks while the engine is running in
Step /5.
IS. Start the engine and let it idle for five minutes, then
shut off the engine.
16. Wait approximately five minutes, then remove the
dipstick. Wipe the dipstick clean with a lint -free cloth or
paper towel and reinsert it in the dipstick tube. Remove
the dipstick a second time and check the oil level. Add oil,
if necessary, to bring the level up to the full mark, but do
net overfill.

Diesel fuel injection systems require clean fuel that
meets the fuel requirements specified by the engine manu-
facturer. Due to the close tolerances required in the fuel
injection system, diesel engines are particularly suscepti-
ble to dirt or other contaminants in the fue l. Use only clean
