IMPORTANT: If antifouling protection is required for the boat hull or boat transom, you can use copper‑based paint if it is not
prohibited by law. If you are using copper based antifouling paint, observe the following precaution:
•
Avoid an electrical interconnection between the Mercury MerCruiser product, anodic blocks, or MerCathode system and
the paint by allowing a minimum of 40 mm (1‑1/2 in.) unpainted area on transom of the boat around these items.

NOTE: Sterndrive and transom assembly can be painted with a good marine paint or an antifouling paint that does not
contain copper or any other material that could conduct electrical current. Do not paint drain holes, anodes, the
MerCathode system, or items specified by the boat manufacturer.
NOTICE
Washing the MerCathode assembly can damage components and lead to rapid corrosion. Do not use any cleaning
equipment such as brushes or high‑pressure washers to clean the MerCathode assembly.
Do not power‑wash a sterndrive that has a MerCathode assembly. Doing so can damage the coating on the reference wire of
the MerCathode assembly and increase corrosion.
