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.
Installing a rudder anode or trim tab anode will help prevent those parts from corroding.
Flat surfaces are most ideal for the installation of these anodes.
