FLUSHING
ENGINE OVERHEATING
IMPORTANT: Do not run your engine — even for a
brief start-up — without supplying water to it. Refer
to Flushing.
DANGER
DO NOT run the engine indoors or without
adequate ventilation or permit exhaust
fumes to accumulate in confined areas.
Engine exhaust contains carbon monoxide
which, if inhaled, can cause serious brain
damage or death.
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, muddy and debris-laden water, and at ex-
treme trim angles.
WARNING
1
Prevent injury from contact with rotating
propeller by removing the propeller before
flushing.
Flush your engine for at least five minutes with fresh
water as soon as possible after each use in salty,
polluted or brackish water to minimize the formation
of deposits that can clog cooling passages.
Run the engine in a large container of water, such
as a 30-gallon garbage can. If needed, insert a
board between the rim of the can and the engine’s
clamp screws for thickness. Be sure water covers
the engine’s water intakes.
1.
Water intakes
If the stream of water from the water pump indicator
becomes intermittent or stops, reduce speed to idle
and:
•
•
•
•
Shift to NEUTRAL
SHUT OFF the engine;
Raise the engine;
Clean the water intakes and the water pump indi-
cator; and
•
Restart 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 motor and do not attempt to operate
it. See your Dealer.
If you succeed in restoring the water pump indica-
tor’s steady discharge, continue to IDLE the engine
until it cools.
Requirements
After an engine overheat, have your Dealer torque
the cylinder head and exhaust cover screws and
DETERMINE THE CAUSE OF THE OVERHEAT.
•
•
•
Well-ventilated area.
Propeller removed.
Water level 4 in. (10 cm) above the antiventilation
plate.
•
•
Shift handle in NEUTRAL and engine in the nor-
mal operating position.
Engine running at fast idle only.
IMPORTANT: To prevent damage, do not run out-
board above fast idle. Water must flow from the wa-
ter pump indicator. If it does not, shut OFF the
engine and investigate. Refer to Engine Overheat-
ing.
