PROTECTION
Sacrificial Anodes
Galvanic
corrosion occurs in fre sh or salt wa ter.
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 equ ipped with three sacrificial
anodes.
Visually inspect ano des and metal co mponents
below water level. Erosion of anode s is normal
and indicates the anodes are functioning properly.
IMPORTANT:
Anodes that are no t eroding ma y
not be properly grounded. Anodes and the mount-
ing screws must be clean an d tig ht for effective
corrosion protection.
For best anode performance:
•
Replace all anodes that have eroded or disinte-
grated to two-thirds of their original size.
•
Do not p aint or app ly pro tective co atings to
anodes or anode fasteners.
•
Avoid using metal-based antifouling paint on the
boat or outboard.
Testing Procedure – Continuity
Connect ohmmeter leads between engine ground
and anode surface.
The mete r sho uld show little or no re sistance. If
resistance is high, check the following:
•
Remove the an ode and clean the area where
the anode is installed
•
Clean the mounting screws
•
Install the anode and test again.
Metallic Component Protection
Protect metal components on outboards from cor-
rosion. Use the following product s 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 preve nt
corrosion and reduce oxidation:
•
Use a utomotive wa x to prot ect the outboa rd’s
exterior finish from oxidation
•
Clean regularly using clean wa ter and mild
detergent soap
•
Touch-up damage to painted surfaces promptly.
