This aluminum shaft anode is designed for mounting on propeller shafts and fits shafts with a 19 mm diameter. The anode protects the propeller shaft, propeller, and other underwater parts against galvanic corrosion by sacrificing itself.
The anode is two-piece and is clamped directly around the shaft with screws. The contact surface should be cleaned of paint and rust before installation to ensure a direct metal connection between the anode and the shaft.
Aluminum is more active than zinc and can be used in both saltwater and brackish water. All anodes on the same installation must be of the same material, as aluminum and zinc anodes must not be mixed.
