Product details
Magnesium anodes, also called "sacrificial anodes", protect all metal parts below the waterline from corrosion. To prevent corrosion of the hull, the anode oxidises faster than the metal it is protecting, Take, for example, a boat with a steel alloy hull, attaching a magnesium anode protects the hull, as the anode sacrifices itself with its inferior metal grade. The water, which acts as an electrolyte here, varies in its aggressiveness depending on the navigable waters.
Typically anodes have to be replaced once per season. In harsh water conditions, a more frequent replacement schedule might be necessary. Anodes are mounted along the keel. The electric current is higher at the stern post due to the propeller being located there. It is advisable to install several anodes in this area. Anodes should also be mounted on the rudder and propeller shaft. For boats which mainly sail in fresh water, we recommend magnesium anodes, because magnesium has a greater difference to other metals than zinc does.
These nut-shaped anodes are available in different sizes.
Note: From a shaft diameter of 55 mm, the anode has 4 mounting holes.
