Boat Bottom Care
To achieve maximum performance and fuel economy, the boat bottom must be kept clean. Accumulation of marine growth or
other foreign matter can greatly reduce boat speed and increase fuel consumption. To ensure best performance and efficiency,
periodically clean the boat bottom in accordance with manufacturer's recommendations.
In some areas, it may be advisable to paint the bottom to help prevent marine growth. Refer to the following information for
special notes about the use of antifouling paints.
Antifouling Paint
IMPORTANT: Corrosion damage that results from the improper application of antifouling paint will not be covered by the limited
warranty.
You may apply antifouling paint to the
boat hull and boat transom but you must observe the following precautions:
IMPORTANT: Do not paint or pressure‑wash the anodes or the MerCathode system reference electrode and anode. Doing so
will render them ineffective as inhibitors of galvanic corrosion.
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.
a - Painted boat transom
b - Minimum 40 mm (1‑1/2 in.) unpainted area around
transom assembly
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.
