Martyr™ III Cadmium-free Magnesium Anodes for Freshwater ONLY

Use Cadmium-free, magnesium anodes if you only use your boat in freshwater. (Zinc anodes can "passivate" and stop working in freshwater.) Magnesium anodes should not be used in any other water type. If you trailer your boat, and use it in a variety of saltwater, brackish and freshwater locations, aluminum anodes are the best all-around choice for protecting your outboard or outdrive.
