ENGINE OVERHEATING
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.
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 engine 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,
and at extreme trim angles.
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.
After any overheat, have your Dealer:
Torque the exhaust manifold bolts and zinc anode
cover and the cylinder head screws.
Inspect the water pump for excessive wear or dam-
age.
Inspect the water pipe and its O-ring.
Inspect the condition and sealing of the exhaust
manifold gasket.
Inspect the thermostats.
Inspect the engine for leaks.
Inspect water pressure valve.
Check engine oil level.

Should the oil pressure drop to a dangerously low
level, the SystemCheck engine monitor will sound
If the engine overheats, its SystemCheck engine the horn and turn on the “NO OIL” light. Also, the
monitor will sound the warning horn and turn on the
"WATER TEMP" or HOT light. Also, the EMM will
immediately limit the engine’s speed to 3000 RPM.
EMM will immediately limit the engine speed to
3000 RPM. This additional protective feature is re-
ferred to as S.L.O.W. If the engine was running fast-
This additional protective feature is referred to as er than 3000 RPM when the S.L.O.W. system
activated, it will shake noticeable.
In case of low oil pressure:
Shut OFF engine.
If tilted, place the engine in vertical position.
Check the oil level on the dipstick and add oil, if
needed. Refer to Crankcase Oil and Filter and
Engine Specifications.
Examine the oil fill cap and drain screw for evidence
of leakage. Make sure each is tight.
S.L.O.W. If the engine was running faster than
3000 RPM when the S.L.O.W. system activated, it
will shake noticeably.
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; and
If dipstick shows that the oil level is okay, leave the
engine upright and shut off for 10 minutes, then
start it. If the engine still limits itself to about 3000
RPM, see your Dealer.
Restart the engine and run at idle.
IMPORTANT: DO NOT attempt to run your engine
if it repeatedly loses oil pressure. See your Dealer.
