Check the oil level on the dipstick and add oil, if
needed. Refer to Crankcase Oil and Engine
Specifications.
Examine the oil fill cap and drain screw for evidence
of oil leakage and make sure they are tight.
ENGINE OVERHEATING
IMPORTANT: Do not run your engine — even for a
brief start-up — without supplying water to it. Refer
to Flushing.
If the dipstick shows the oil level is okay, leave the
engine upright and shut off for ten minutes, then
start it. If the engine still limits itself to about 2000
RPM, see your Dealer.
While boating, the engine’s water intake must stay
completely submerged and unobstructed. Observe
proper transom height and trim angle. While the en-
gine is running, the engine’s water pump indicator

weeds, muddy and debris-laden water, at extreme
trim angles, or in shallow water drive (if equipped).
The light will come on for a few seconds after the
engine starts. This verifies the warning system is
working.
If the light does not come on, stop the engine and
see your Dealer.
If the light stays on, check the engine oil level and
add oil if necessary.
If the oil level is correct, see your Dealer.
IMPORTANT: If you operate the engine with this
light on, severe engine damage can result.
IMPORTANT: Do not rely on the low oil pressure
light to indicate the need to add oil. Be sure to peri-
odically check the engine oil level. If the oil level is
low, severe engine damage can result.

If the system activates for no apparent reason, see
your Dealer.
IMPORTANT: You must restore cooling to the en-

After any overheat, have your Dealer:
Torque the cylinder head screws.
Inspect the water pump for excessive wear or dam-
age.
Inspect the thermostats.
Inspect the engine for leaks.
Check engine oil level.
