The set is made of magnesium for superior performance in fresh water, avoids cadmium for environmental safety, and meets Mil-Spec A-21412(SH) standards. It replaces the key zinc or sacrificial parts around the gimbal housing, ventilation plate, trim rams and prop-to-gear-housing junction so you can maintain effective corrosion control season after season.\u003c\/p\u003e\n\n\u003ch3\u003eWhat exactly is included in the kit and how does each part function?\u003c\/h3\u003e\n\u003cp\u003eThis kit bundles every anode element used on the Alpha One Gen II lower unit to create a balanced sacrificial system.
