Product Overview
If you use your boat in saltwater or in brackish water, these aluminum mil-spec anodes are your best choice for protecting metal rudders and trim tabs against galvanic corrosion. Used in saltwater, aluminum anodes protect better and last longer than zinc. Used in brackish water, aluminum anodes are superior to zinc which can passivate" and not work at all or magnesium anodes which corrode too rapidly. Aluminum anodes are also lighter than zinc and contain no cadmium which is a substance of environmental concern. Offered with hex-head stainless steel machine screws.
