This Tecnoseal zinc shaft anode 55/25 mm protects the boat shaft against galvanic corrosion by corroding itself instead of the shaft and other metal parts.
The shaft anode is made of zinc and features metal inserts at the bolt holes. It is designed for mounting directly onto the shaft, where tight contact between the metal surfaces is necessary for proper function.
Clean the shaft of paint and rust before mounting so that there is direct metal contact between the anode and the shaft. Tighten the bolts firmly so that the anode is secure and does not slip during operation.
