Shaft Anode – Sacrificial Zinc & Aluminum Collar Anode for Marine Propeller Shafts

Protect your propeller shaft, strut, and other underwater running gear from galvanic corrosion with a quality shaft anode. These sacrificial collar anodes are designed to clamp securely around the propeller shaft and corrode first, helping preserve expensive driveline components in both saltwater and brackish or freshwater applications depending on anode material selection.

Shaft anodes are a simple but essential part of routine marine maintenance. By attracting corrosive activity away from the shaft and surrounding metal hardware, they help extend service life, reduce damage, and support more reliable long-term performance below the waterline.
