Anode Replacement

Protect Your Boat From Underwater Corrosion

Regular zinc anode inspections and timely replacement help protect your propeller, shaft, struts, trim tabs, and other underwater metals from galvanic corrosion.

Why Zinc Anodes Matter

Zinc anodes are your boat’s first line of defense against galvanic corrosion. They are designed to wear away before expensive underwater metal components, helping protect your propeller, shaft, struts, trim tabs, and other running gear.

What Happens If Zincs Aren't Replaced?

Zinc anodes are designed to sacrifice themselves to protect your boat’s underwater metals. Once they’re depleted, corrosion can begin affecting expensive components such as propellers, shafts, struts, trim tabs, and other underwater hardware.

Regular inspections and timely replacement help prevent costly repairs and extend the life of your running gear.

Routine zinc replacement is inexpensive compared to repairing corrosion damage.

Not Sure If Your Zincs Need Replacement?

Schedule an inspection and we’ll check your zincs, explain their condition, and only recommend replacement when it’s actually needed.
