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 Dealer for re-
placements.
Anti-corrosion Anodes
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.
NOTICE
NEVER paint the anode, its
fasteners, or its mounting surface. Paint-
ing will reduce its corrosion protection.

FLUSHING

Flush the outboard with fresh water following
use in brackish, salt or polluted water to
minimize the accumulation of scale and silt
deposits 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.

SERVICE

NOTICE
board in the recommended vertical posi-
tion, be sure the cooling system is
drained completely. Never place the gear-
case higher than the powerhead. Any
water remaining in the exhaust passages
can run into the cylinders and cause seri-
ous damage.
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) Remove propeller and place the shift lever
in NEUTRAL position.
3) Connect garden hose to flushing device
and install flushing device on gearcase.
4) Turn on the water. Keep the water pres-
sure between 20 and 40 psi (140 to
300kPa).
