Help protect your Max-Prop propeller with a zinc anode. Make sure you always keep your anodes in good condition. They should be replaced at least once a year. The Max-Prop anode has a metal ring molded into it. This metal ring goes around the entire diameter where the screws secure the anode to the propeller. This ring distributes the electric current through the entire anode giving it a much longer life. Even with the metal ring, Seaview Progress recommends, when installing the anode, to clean the flat surface and the back of the propeller so as to ensure good contact between the anode and the propeller. . This will greatly increase the life of the anode. It’s always a good idea to have zinc anodes available, you never know when you will need them.
