Engine Maintenance; Checking Fluid Levels - PCM HO303 MPI Owner's Operation And Maintenance Manual

ENGINE MAINTENANCE

Refer to the MAINTENANCE SCHEDULE for a complete
listing of required maintenance and the frequency at
which it should be performed. While some procedures
may be performed by the owner/operator, PCM
Engines strongly recommends that all engine service
and maintenance be performed by an authorized
PCM Engines Premier Dealer. Before performing any
maintenance or repair procedure not covered in this
manual, it is strongly recommended that a PCM Engines
repair manual be purchased and read thoroughly.

CHECKING FLUID LEVELS

Engine Crankcase Oil
CAUTION
Do Not overfi ll engine crankcase with oil.
Excessive oil can lead to premature engine
component failure and/or loss of performance.
IMPORTANT: The engine oil level must be checked
while the boat is in its normal, level, at rest position
on the water. Excessive wave action side to side
or fore and aft may cause you to obtain erroneous
readings. If the oil level is being checked while
the boat is on a trailer, ensure the trailer is on level
ground, then adjust the trailer so the boat is at its
normal, at rest position. Excess water in the bilge
and, if equipped, ballast systems must be purged
when checking the engine oil level, otherwise
erroneous readings may be obtained.
1. Stop the engine, if running. Allow approximately
5 minutes for the oil to drain back into the oil pan.
2. Remove the dipstick, wipe it clean, and reinstall
it until it is within two (2") inches of being fully
seated. Slowly move the dipstick up and down
approximately one-half (1/2") several times; then
fully seat the dipstick into the dipstick tube.
3. In order to obtain an accurate reading, wait two
minutes for the oil to stabilize on the dipstick.
Remove the dipstick and observe the oil level.
The oil level must be between the "FULL" and
"ADD" marks. If the oil level is below the "ADD"
mark, add specifi ed oil to bring the level up to,
but not over, the "FULL" mark on the dipstick.
If the oil level is above the "FULL" mark on the
dipstick, remove the excess oil. (Figure 11-1)

The machinery space must be closed anytime the
engine is running to prevent injury to you or others
on board. Never operate the engine with the engine
machinery space open while someone is in the
machinery space, either closed or open. Never
open the machinery space unless the engine is shut
off and the engines rotating parts are stationary.
Rotating machinery can cause injury and even death
if an accident should occur. Extreme care must be
exercised if a problem exists that requires operation
of the engine with the machinery space open. IT
IS RECOMMENDED THAT UNCOVERED ENGINE
OPERATION BE ATTEMPTED BY TRAINED AND
QUALIFIED SERVICE PERSONNEL ONLY.
