MAINTENANCE
ANTI-CORROSION PROTECTION
3
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.
IMPORTANT:
The anode securing screw
should be covered with silicone sealant.
Testing Procedure – Continuity
Calibrate multimeter on “HIGH” ohm scale.
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 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.
•
Protect moving components with appropriate
lubricants.
