High-quality magnesium propeller anode specifically designed for Mercury Alpha I and Bravo I drives. This sacrificial anode is mounted directly onto the propeller shaft as a nut and reliably protects the propeller and drive shaft from galvanic corrosion. As an original Mercury replacement part (Part No. 55989), it guarantees a perfect fit and optimal protection for all metallic components in the propeller area.
Sacrificial anodes are essential for corrosion protection of boat propulsion systems. They sacrifice themselves through an electrochemical reaction, thereby protecting more expensive propulsion components such as propellers, propeller shafts, and housing parts from corrosion. Regular inspection and timely replacement are crucial for maintaining the long-term value of your propulsion system.
