Zinc & Anode Replacement Services

Zinc anodes are your boat's first line of defense against galvanic corrosion. These sacrificial metals protect your expensive underwater components like props, shafts, rudders, and thru-hulls from destructive corrosion in saltwater.

What Are Zincs and Why Do They Matter?

When different metals are submerged together in saltwater, they create a galvanic cell that causes corrosion. Zinc anodes are more reactive than your boat's metal components, so they corrode first, protecting your valuable equipment. When zincs are depleted, corrosion attacks your props, shafts, and other underwater metals instead.

In South Florida's warm saltwater, zincs can deplete quickly. Regular inspection and replacement is essential to prevent costly damage to your boat's underwater metals. A few dollars in zincs can save thousands in prop and shaft replacement.

Our Zinc Inspection and Replacement Service

When to Replace Your Zincs

Zincs should be replaced when they are approximately 50% depleted. Waiting until they are completely gone leaves your boat unprotected. In South Florida waters, most boats need zinc replacement every 3-6 months, depending on water conditions, electrical systems, and time in the water.

We recommend having your zincs inspected monthly as part of routine hull cleaning. This allows us to monitor zinc condition and replace them at the optimal time, ensuring continuous protection.

Signs Your Zincs Need Attention

If you notice pitting on your prop, shaft, or other underwater metals, your zincs may not be providing adequate protection. Rough or corroded metal surfaces, unusual deterioration, or complete zinc depletion are all signs that immediate attention is needed.

Regular inspection catches problems before expensive damage occurs. Our divers check zinc condition during every hull cleaning and alert you when replacement is needed.
