ENGINE MONITORING
ENGINE OVERHEATING
Do not run your outboard—
even for a brief start-up—without supply-
ing water to it. Refer to Flushing on page
46.
While boating, the outboard’s water intakes
must stay completely submerged and unob-
structed. Observe proper transom height and
trim angle. While the outboard is running, the
outboard’s water pump indicator must dis-
charge a steady stream of water. Check the
indicator often, especially when operating in
weeds, mud and debris-laden water, and at
extreme trim angles.
If the engine overheats, the engine monitor
will sound the warning horn and turn on the
“WATER TEMP” or “HOT” light. Also, the
S.A.F.E. (Speed Adjusting Failsafe Electron-
ics) mode will immediately limit the engine’s
speed to 1200 RPM. If the engine was run-
ning faster than 1200 RPM when the S.A.F.E.
mode activated, it will shake noticeably. The
protection system must be RESET before the
engine will operate at speeds over 1200 RPM.
Under certain conditions the EMM will shut off
the engine.
To RESET the system:
• The engine must be shut off and the cooling
temperature restored.
IF the S.A.F.E. mode activates and the
stream from the water pump indicator be-
comes intermittent or stops, reduce speed to
idle and:
1) Shift to NEUTRAL.
2) SHUT OFF the engine.
3) Tilt the outboard up.
4) Clean the intake screens of any blockage.
5) Clean the water pump indicator of any
blockage.
6) Lower the outboard.
7) Restart the engine and run at idle.
IF cleaning the screens and indicator does
not restore the water pump indicator’s steady
discharge, the engine will operate only in “get
home” mode. Return to harbor immediately.
See your Dealer.
IF cleaning the screens and indicator does re-
store the water pump indicator’s steady dis-
charge, you might have to run for two minutes
in NEUTRAL to allow the engine to cool and
the light to go off.
IMPORTANT: If cooling is not restored, the
EMM will identify a progressive overheating
condition and shut off the engine. The “WA-
TER TEMP” or “HOT” light will flash. The en-
gine will not restart until the engine is allowed
to cool.
After any overheat causing engine shutdown,
see your Dealer for:
• Inspection of the water pump for excessive
wear or damage.
• Inspection of the thermostats.
Although the S.A.F.E. mode
can help prevent engine damage, it does
not guarantee you can run your engine
indefinitely without engine damage.
