These anodes are made with an aluminum alloy which is specially formulated for marine anode use. They last longer than zinc anodes and, utilizing a less toxic activator, are safer for the environment.
These replacement aluminum anodes fit over the corresponding bronze shaft nuts installed on the end of the propeller shaft.
Cast-in stainless steel mounting insert provides better grounding and prevents the anode from loosening, even as it is being consumed.
