ENGINE OVERHEATING
ANTI-CORROSION ANODES
The outboard is equipped with one or more
anodes that protect it from galvanic corrosion.
Disintegration of the anode is normal and in-
dicates it is working. Check each anode peri-
odically. Replace anodes smaller than 2/3
their original size.
IMPORTANT: Do not run your outboard with-
out 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 completely submerged and unob-
structed. Observe proper transom height and
tilt 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, muddy and debris-laden water, and at
extreme trim angles.
Galvanic corrosion destroys underwater met-
al 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.

engine revolutions to signal the operator.
•
If the temperature becomes critical, engine
speed is limited to 2500 RPM.
SALT WATER
Upon removal from salt water, leave outboard
in a vertical position until its cooling system
has drained. During long periods of mooring,
tilt the gearcase out of the water, except in
freezing temperatures. Flush the outboard, if
desired. Refer to Flushing on page 32.
The protection system must be RESET be-
fore 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 in-
termittent or stops, stop the engine and:
1)
2)
Clean the intake screens of any blockage.
Clean the water pump indicator of any
blockage.
3)
Restart the engine and run at idle.
IF cleaning the screens and indicator does
not restore the indicator stream, return to har-
bor as soon as possible.
