ENGINE OVERHEATING
If the stream from the water pump indicator be-
comes intermittent or stops, reduce speed to idle
and:
Shift to NEUTRAL;
SHUT OFF the engine;
IMPORTANT: Do not run your engine — even for a
brief start-up — without supplying water to it. Refer
to Flushing.
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
must discharge a steady stream of water. Check
the indicator often, especially when operating in
weeds, muddy and debris-laden water, at extreme
trim angles, or in shallow water drive (if equipped).
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.
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: You must restore cooling to the en-
gine to avoid serious engine damage.
