ENGINE OVERHEATING
IMPORTANT: Do not run your outboard without supplying
water to it. Refer to FLUSHING on page 32. Water pump
damage can occur in just a few seconds.
While boating, the outboard’s water intakes must stay com-
pletely submerged and unobstructed. Observe proper tran-
som height and tilt angle. While the outboard is running, the
outboard’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.
Galvanic corrosion destroys underwater metal parts and
can occur in fresh or salt water; however, salt, brackish,
and polluted waters will accelerate corrosion.
Metal-based antifouling paint on the boat or outboard and
the use of improperly installed shore power in the area of
your moored boat will also accelerate corrosion.
IMPORTANT: NEVER paint the anode, its fasteners, or its
mounting surface. Painting will reduce its corrosion protec-
tion.

Water intake screens
Water pump indicator
If the engine overheats:
•
The EMM interrupts the ignition once per 50 engine rev-
olutions to signal the operator.
•
If the temperature becomes critical, engine speed is lim-
ited to 2500 RPM.
The protection system must be RESET before the engine
will operate normally.
To RESET the system:
•
The engine must be shut off and the correct operating
temperature restored.
IF the overheat warning mode activates or the water pump
indicator stream becomes intermittent or stops, stop the
engine and:
1)
2)
3)
Clean the intake screens of any blockage.
Clean the water pump indicator of any blockage.
Restart the engine and run at idle.
IF cleaning the screens and indicator does not restore the
indicator stream, return to harbor as soon as possible.
ANTI-CORROSION ANODES
The outboard is equipped with one or more anodes that
protect it from galvanic corrosion. Disintegration of the an-
ode is normal and indicates it is working. Check each an-
ode periodically. Replace anodes smaller than 2/3 their
original size.
