Boat Zincs and Anodes

Boat Zinc Anodes & Marine Sacrificial Anodes for Corrosion Protection

Boat zinc anodes, also known as marine sacrificial anodes or boat zincs, are an essential part of protecting underwater metal components from galvanic corrosion. Installed on components such as bronze propellers, propeller shafts, metal struts, rudders, trim tabs, and other underwater hardware, sacrificial anodes are designed to corrode in place of your valuable marine equipment.

Galvanic corrosion occurs when dissimilar metals are electrically connected while immersed in water. Without proper marine corrosion protection, underwater metal components can gradually corrode, weaken, and deteriorate. A properly installed sacrificial anode provides protection by becoming the metal that corrodes first, helping extend the service life of your boat's underwater components.

At U.S. Boating Marine Supplies, shop a wide selection of boat anodes and marine sacrificial anodes, including zinc anodes, magnesium anodes, and aluminum anodes for a variety of boats and water conditions.
