Sacrificial Anodes & Replacement Zincs

Fisheries Supply provides marine grade sacrificial anodes from quality manufacturers protecting vessels from corrosion. Also called zincs or galvanic anodes, these components are highly active metals that are used to prevent less active materials, like metal hulls, props and other underwater parts, from corroding. We offer a full range of boat zincs tailored for salt or freshwater use including shaft, outboard, trim tab and pencil anodes plus hull and strap configurations. Regular inspection of condition helps determine replacement cycles. Though limited in capacity, when properly matched to vessel service and surroundings, zincs provide cost-effective protection for years. Our representatives help select the right zinc anodes for your boat's underwater metal components. Consider details like material compatibility, positioning and desired protection levels. Proper installation places zincs lower on outdrives while maximizing water flow contact. Trust top brands found in our online inventory to safeguard investments from electrolysis damage on the water.
