This Tecnoseal aluminum shaft anode 65/40 mm is mounted around the propeller shaft and protects the propeller shaft, propeller, and associated fittings against galvanic corrosion.
The anode fits shafts with a 40 mm diameter and can be used in both saltwater and brackish water. Aluminum has a longer service life than zinc under the same conditions and weighs approximately 2.5 times less.
All anodes in the same system must be made of the same material. If aluminum and zinc are mixed, the aluminum anode will protect the zinc anode instead of the boat's metal parts. Clean the contact surface of paint and rust before installation so that there is a direct metal connection between the anode and the shaft.
