This Bera zinc shaft anode is designed for boat shafts with a diameter of 50 mm. The anode protects the shaft, propeller, and other metal parts from galvanic corrosion by sacrificing itself instead of the more expensive parts in the propeller system.
The anode has an external diameter of 85 mm and is made of zinc. Its wide construction makes it suitable for mounting directly onto the shaft, where tight metal-to-metal contact is required for proper function.
The metal insert at the bolt hole ensures secure fastening. Clean the shaft of paint and rust before installation, and tighten the bolts firmly so the anode does not slip during operation.
