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-

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: Do not rely on the low oil pressure
light to indicate the need to add oil. Be sure to peri-

low, severe engine damage can result.

OVER-REVOLUTION LIMITING SYSTEM
Shift to NEUTRAL;
This system is activated when engine speed ex-
ceeds maximum recommended speed for more
than 10 seconds.
If this system activates, engine speed will automat-
ically be reduced to approximately 3000 RPM.
This system must be reset by moving the throttle to
the idle position for about one second to restore full
engine operation.
SHUT OFF the engine;
Tilt the motor up;
Clean the intake screen of any blockage;
Clean the water pump indicator of any blockage;
Lower the motor; and
Restart the engine and run at idle.
IF cleaning the screen and indicator does not re-
store the water pump indicator’s steady discharge,
SHUT OFF the engine and do not attempt to oper-
ate it. See your DEALER.
other factors (like “over-trimming” or “ventilation”) IF cleaning the screen and indicator does restore
the water pump indicator’s steady discharge, con-
tinue to idle the engine until it cools.
IMPORTANT: The Over-Revolution Limiting Sys-
tem will not be activated at recommended maxi-
mum throttle unless propeller pitch is insufficient or
prevail.
If the system activates for no apparent reason, see
your DEALER.
IMPORTANT: You must restore cooling to the en-
gine to avoid serious engine damage.
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.
