Perhaps the most versatile anode material, the specially formulated aluminum alloy used in these anodes is an ideal choice as it not only works better than zinc anodes in saltwater, it protects your boat, outboards, and stern drive units in brackish water, as well. If your boat is used in both salt and tidewater environments for extended periods, aluminum is the best all around choice.
All anodes included for 100% proper corrosion protection
Can be used in both salt and brackish water; does not offer adequate protection in pure freshwater environments
