ENGINE OVERHEATING
WARNING
IMPORTANT: Do not run your engine — even for a
brief start-up — without supplying water to it. Refer
to Flushing.
Prevent injury from contact with rotating
propeller; remove the propeller before
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, muddy and debris-laden water, and at ex-
treme trim angles.
1)
Place the engine in vertical position in a well-
ventilated area with good drainage.
Install flushing device and garden hose.
Place the remote control lever in NEUTRAL
with the propeller removed.

4)
Start the water — keep pressure between 20
to 40 psi (140 to 300 kPa).

If the engine overheats, its System Check engine
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.
This additional protective feature is referred to as
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.
To RESET the S.L.O.W. protection system, slow
the engine to 800 RPM or shut it OFF.
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:

Start the engine — run it at idle only and
flush it for at least five minutes. Check the
water pump indicator. A steady stream of wa-
ter must flow. If it does not, shut OFF the en-
gine and investigate. Refer to Engine
Overheating.
6)
Leave the outboard in vertical position long
enough to completely drain the powerhead.
