This aluminum shaft anode protects the propeller shaft, propeller, and associated metal parts from galvanic corrosion by degrading itself instead of the more expensive metal components.
The anode fits shafts with a 25 mm diameter and is used on sailboats and motorboats in saltwater and brackish water. The two-piece anode is locked onto the shaft with two bolts, typically 5–10 cm in front of the propeller.
Aluminum provides approx. 70% more ampere-hours over its service life than a comparable zinc anode and weighs approx. 2.5 times less. Do not mix aluminum and zinc anodes on the same installation, as the entire anode system should be either aluminum or zinc.
