ANTI-CORROSION
PROTECTION
Sacrificial Anodes
Galvanic
corrosion occurs in fresh or salt water.
Salt, brackish, and polluted water can accelerate
corrosion. “Sacrificial” anodes are intended to pro-
tect the underwater metal components of the out-
board from galvanic corrosion.
Outboards are equipped with three sacrificial
anodes.
Visually inspect anodes and metal components
below water level. Erosion of anodes is normal
and indicates the anodes are functioning properly.
IMPORTANT:
Anodes that are not eroding may
indicate that the anodes are not properly
grounded. Anodes and the mounting screws must
be clean and tight for effective corrosion protec-
tion.
For best anode performance:
•
Replace all anodes that have eroded or disinte-
grated to two-thirds of their original size.
•
Do not paint or apply protective coatings to
anodes or anode fasteners.
•
Avoid using metal-based antifouling paint on the
boat or outboard.
Testing Procedure – Continuity
Connect meter leads between engine ground and
anode surface.
The multimeter should indicate little or no resis-
tance. If resistance is high, check the following:
•
Remove the anode and clean the area where
the anode is installed.
•
Clean the mounting screws.
•
Install the anode and do the test again.
Metallic Component Protection
Protect metal components on outboards from cor-
rosion. Use the following products to minimize
corrosion.
•
Anti-Corrosion Spray
provides a heavy, waxy
coating to protect components.
•
“6 in 1” Multi-Purpose Lubricant
provides a thin
film of anti-corrosion protection.
Exterior Finishes
Maintain the outboard’s exterior finish to prevent
corrosion and reduce oxidation.
•
Use automotive wax to protect the outboard’s
exterior finish from oxidation.
•
Clean regularly using clean water and mild
detergent soap.
•
Touch-up damage to painted surfaces promptly.
The upper and lower motor covers use molded-in
color technology. Surface scratches on the covers
can be polished out with buffing compound.
Minor scratches can be repaired as follows:
•
Sand the affected area with 800-grit sandpaper.
•
Wet sand the area with 1200-grit sandpaper.
•
Polish with a fine grade of buffing compound.
