This zinc shaft anode for 25 mm propeller shaft protects the propeller shaft and associated metal parts from galvanic corrosion by sacrificing itself.
The anode is mounted directly onto the shaft using the pre-drilled holes. The shaft must be cleaned of paint, rust, and grease before installation to ensure direct metal-to-metal contact.
The screws should be tightened firmly so that the anode is secure and does not slip during operation. Zinc performs poorly in freshwater, where magnesium anodes are recommended instead.
