This aluminum shaft anode for a 38 mm propeller shaft protects the propeller shaft and propeller against galvanic corrosion by corroding itself instead of the more expensive metal parts.
The anode is designed to be mounted around the shaft and can be used in both salt water and brackish water. Aluminum can replace traditional zinc anodes and has a longer service life as well as higher active protection over time.
The anode is installed as a two-piece split anode with bolts without removing the propeller. The shaft must be cleaned of paint and oxides before installation so that there is direct metal-to-metal contact between the anode and the shaft.
