Anti-Corrosion Anodes
Your 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. See your service center for
replacements.
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 anti-fouling 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.
Flushing
Flush the outboard with fresh water following
use in brackish, salt or polluted water to mini-
mize the accumulation of scale and silt depos-
its in cooling system passages. The outboard
can be flushed on the trailer or at dockside.
Place outboard in vertical (down) position in a
well ventilated area.
Using Lower Engine Cover Flushing
Port
1) Place the outboard in an area with good
drainage.
2) Connect garden hose to flushing port.
3) Turn on the water. It is not necessary to
run the engine for a good flushing.
4) Leave the outboard in vertical position long
enough to completely drain the power-
head.
Using Gearcase Flushing Device
1) Place the outboard in an area with good
drainage.
2) Temporarily cover the two small auxiliary
water inlet holes on each side of the gear-
case with heavy tape to insure enough wa-
ter travels to the powerhead from the water
intakes. Water can drain from auxiliary in-
lets, resulting in engine overheat Remem-
NOTICE
NEVER paint the anode, its fasteners, or
its mounting surface. Painting will
reduce its corrosion protection.

NOTICE
If you cannot store the outboard in the
recommended vertical position, be sure
the cooling system is drained com-
pletely. Never place the gearcase higher
than the powerhead. Any water remain-
ing in the exhaust passages can run into
the cylinders and cause serious damage.
