Inhibiting Corrosion
In addition to the corrosion protection devices, follow these steps to inhibit corrosion:
1. Paint your power package. See Painting the Power Package.
2. Spray power package components on the inside of the boat annually with Corrosion Guard to protect the finish from dulling
and corrosion.
3. Keep all lubrication points well lubricated.
Painting the Boat
IMPORTANT: The limited warranty does not cover corrosion damage as a result of improper paint application.
IMPORTANT: Paint renders anodes and the MerCathode system ineffective as inhibitors of galvanic corrosion.
The underwater portion of the drive can be painted in order to inhibit marine growth. Conventional anti‑fouling coatings (bottom
paint) can be used, as well as more specialized foul‑release coatings (like PropSpeed®). If bottom paint is used, best results will
be seen using paint containing copper oxide plus an algaecide additive.
NOTE: PropSpeed is a registered U.S. trademark of Oceanmax International, Limited.
When painting a drive or boat hull with anti‑fouling paint, observe the following:
