Zinc & Screw Sizing Info Help protect your Max-Prop with a Zinc Anode. Make sure that you always keep the Anodes in good condition. They must 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 attach the Anode to the propeller. This ring disburses the electrical current through the entire Anode giving it a much longer life
