What are Sacrificial Anodes?

Sacrificial anodes are small but critical components made from metals like zinc that help prevent corrosion on your boat’s metal parts. By intentionally corroding before your hull, propellers, and shafts do, these anodes “sacrifice” themselves to protect your investment. Without them, saltwater and electrolysis can quickly cause expensive damage. That’s why regular replacement is essential for any responsible boat owner.

Our Underwater Anode Replacement Process

We begin with a careful dive inspection to evaluate your current anodes and check surrounding underwater surfaces for signs of corrosion or wear. If replacement is needed, we remove spent anodes and install high-quality zinc anodes tailored to your vessel’s size and needs. Every step is handled by experienced, licensed divers who take pride in doing the job right—clean, secure, and built to last.

Signs Your Vessel Needs New Anodes

Pitting or Flaking
Corrosion on metal parts may indicate failing anodes or stray current issues.

Worn or Missing Anodes
If anodes are over 30–50% gone, they can’t protect your boat effectively.

Discoloration or Buildup
Crusty deposits near fittings often signal electrolysis or galvanic corrosion.

Electrolysis Nearby
Corrosion on neighboring boats may point to a larger marina-wide issue.

Anodes Over Paint
Installed over paint, anodes can’t make proper contact and won’t work.

Pacified Anodes
Smooth or inactive anodes aren’t doing their job and need replacing.

Still Unsure?
A quick inspection brings peace of mind and helps prevent costly repairs.

Choosing the Right Metal for South Florida Waters

In South Florida’s warm, salt-heavy waters, zinc anodes are a trusted choice for protecting your vessel’s underwater components. They’re well-suited for saltwater environments and help prevent corrosion on critical parts like propellers, shafts, and trim tabs.

“They keep everything spotless below the waterline including bottom paint, running gear and replacing the occasional zinc.”

-Michael Cutter, Sea Ray 380 Sundancer
