Zinc Anode Replacement

Zinc anodes are your boat’s first line of defense against corrosion. Known as sacrificial anodes, they sacrifice themselves to prevent electrochemical reactions that would otherwise damage your vessel’s propellers, shafts, and other underwater metals.

Why Zinc Anode Replacement is Important

Zinc anodes, also known as sacrificial anodes, are metal structures that are essential for preventing galvanic corrosion. This process occurs when different metals in contact with seawater generate electrical currents, leading to the corrosion of underwater metal parts like propellers, shafts, and various other fittings.

Zinc anodes protect your boats critical systems by sacrificing themselves before more expensive components. However, once anodes become more than 50% depleted, they lose effectiveness and must be replaced quickly.
