This Tecnoseal zinc anode for 50 mm propeller shaft protects the propeller shaft and associated metal parts from galvanic corrosion by corroding instead of the more expensive parts.
The anode is mounted directly onto the shaft and is intended for use in saltwater. The inner diameter is 50 mm, so it fits a propeller shaft with the same shaft diameter.
The anode is split into two halves, which are placed around the shaft and fastened with bolts through the two mounting holes. Clean the shaft of paint and rust before installation to ensure direct metal contact between the anode and the shaft.
