ENGINE OVERHEATING
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 intakes 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, mud and debris-laden water and at extreme
trim angles.
1. Water intake screens
2. Water pump indicator
If the engine overheats, its
SystemCheck
engine
monitor will sound the warning horn and turn on the
“WATER TEMP” or HOT light. Also, the
S.L.O.W.
protection system will immediately limit the engine’s
speed to 1200 RPM. If the engine was running fast-
er than 1200 RPM when the
S.L.O.W. system acti-
vated, it will shake noticeably. The protection
system must be
RESET before the engine will op-
erate at speeds over 1200 RPM. Under certain con-
ditions the
EMM
will shut off the engine.
The following conditions must be met to RESET the
system:
The engine must be shut off and the cooling tem-
perature restored.
IF the S.L.O.W. protection system activates and the
stream from the water pump indicator becomes in-
termittent or stops, reduce speed to idle and:
Shift to NEUTRAL.
SHUT OFF the engine.
Tilt the motor up.
Clean the intake screens of any blockage.
Clean the water pump indicator of any blockage.
Lower the motor.
Restart the engine and run at idle.
IF cleaning the screens 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 screens and indicator does restore
the water pump indicator’s steady discharge, you
might have to run for two minutes in NEUTRAL to
allow the engine to cool and the light to go off.
If the warning light stays on after two minutes,
STOP the engine and see your Dealer.
IMPORTANT: You must restore cooling to the en-
gine to avoid serious engine damage. If you do not
restore cooling to the engine the
EMM will identify a
progressive overheating condition and shut off the
engine. The "WATER TEMP" or HOT light will flash.
The engine will not restart until the engine is al-
lowed to cool.
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.
