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.
1
1. Stern bracket anode
2. Propeller shaft bearing housing anode
(inside of gearcase housing)
3. Gearcase housing anode
Visually inspect anodes and metal components
below water level. Erosion of anodes is normal
and indicates the anodes are functioning properly.
Anodes that are not eroding may
IMPORTANT:
not be properly grounded. Anodes and the mount-
ing screws must be clean and tight 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 paint or apply protective coatings to
•
anodes or anode fasteners.
Avoid using metal-based antifouling paint on the
•
boat or outboard.
ANTI-CORROSION PROTECTION
Testing Procedure – Continuity
Connect ohmmeter leads between engine ground
and anode surface.
1
1. Meter lead to anode
The meter should show little or no resistance. 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 test again.

Metallic Component Protection

2
Protect metal components on outboards from cor-
rosion. Use the following products to minimize
DR5082 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.
•
Protect moving components with appropriate
•
lubricants.
