This aluminum shaft anode is mounted directly onto the propeller shaft and protects the shaft, propeller, and associated metal parts against galvanic corrosion. The anode corrodes instead of the more expensive metal parts and is suitable for use in saltwater and brackish water.
The aluminum anode can replace traditional zinc anodes and provides up to 70% more ampere-hours over its lifespan than a comparable zinc anode. It is cadmium-free, lighter than zinc, and can be used in both saltwater and brackish water.
The anode is two-part and is clamped around the shaft with bolts. The shaft must be cleaned of paint, rust, and grease before installation to ensure direct metal-to-metal contact between the anode and the shaft. All anodes on the boat should be of the same material, and zinc and aluminum should not be mixed.
