This 3.5 kg zinc anode is designed for hull mounting on boats sailing in saltwater. The anode is mounted below the waterline and is used to protect the boat's metal parts against galvanic corrosion.
The zinc anode corrodes instead of more expensive metal parts such as propeller shafts, fittings, and hull plates. For proper effectiveness, there must be a direct metal connection between the anode and the hull.
When mounting, clean the contact surface of paint and rust, then tighten the screws so the anode is secure and has good electrical contact. Zinc anodes are only suitable for saltwater.
Important features
For use on boats in saltwater
Bolted to the hull below the waterline
