Whether you cruise in saltwater, freshwater, or brackish conditions and need a collar shaft anode, disc anode, or engine-specific anode: find the exact protection for your vessel right here.

The specific anode products on this page

Our collection on this page features the following anodes and accessories:

• Zinc Anodes (Saltwater): Zinc propeller shaft anodes, disc anodes, and transom anodes for maximum cathodic protection in marine environments.

• Aluminum Anodes (Brackish & Saltwater): Lightweight aluminum sacrificial anodes suited for brackish water and universal protection for aluminum saildrives and sterndrives.

• Magnesium Anodes (Freshwater): High-output magnesium anodes designed specifically for rapid response and protection in inland freshwater.

• Shaft & Saildrive Anodes: Split collar shaft anodes in various millimeter sizes, rudder disc anodes, and dedicated saildrive ring anodes.

• Engine & Transom Anodes: Block and transom anodes with pre-drilled mounting holes, alongside engine pencil anodes (including brass plugs) for internal cooling circuit protection.

Reliable corrosion protection for all water conditions

All anodes on this page are manufactured to strict metallurgy standards to ensure predictable and even consumption. This prevents costly electrolytic damage to propellers, bronze thru-hulls, and steel or aluminum hulls.
