This zinc hull anode protects the boat's underwater metal parts against galvanic corrosion in saltwater. The anode acts as a sacrificial anode and corrodes instead of screws, fittings, and other exposed metal parts on the hull.
The anode is mounted directly onto the hull or other metal parts below the waterline. The contact surface must be cleaned of paint and rust before installation to ensure a direct metal connection.
Zinc anodes are intended for saltwater only. In freshwater and brackish water, other types of anodes must be used, as zinc does not function sufficiently under these conditions.
