Lenco 3 3/4" Sacrificial Anode Pack of 2

The Lenco 3 3/4" Sacrificial Anode Pack of 2 is an essential marine corrosion protection system for boat owners who spend serious time on the water. If you've been boating for any length of time, you know that saltwater and freshwater environments attack your vessel's metal hardware relentlessly—and ignoring corrosion means expensive repairs down the line. These zinc anodes work silently beneath the surface, sacrificing themselves to protect your boat's hull, shaft, and other critical metal components from electrolytic corrosion and rust.

Lenco Marine's zinc sacrificial anodes operate on a proven electrochemical principle: zinc is more reactive than the steel and aluminum components on your boat, so it corrodes first and draws corrosive current away from your hull and propeller. Each anode in this pack of 2 measures 3 3/4 inches and comes with a mounting screw for secure installation on your boat's through-hull fitting or shaft log. The zinc composition and size are engineered to provide reliable, long-lasting protection in both saltwater and brackish environments, and the convenient clamshell packaging keeps spares organized and ready for replacement when needed.

Serious anglers and cruising boaters should keep replacement anodes on hand—inspection and replacement are routine maintenance tasks that extend the life of your investment. The 3 3/4" size fits standard Lenco through-hull anode systems, making this pack a direct replacement for worn units. Whether you're fishing coastal waters, running up rivers, or moored in a marina, these sacrificial anodes are your silent defense against corrosion, ensuring your vessel stays sound and your hardware stays protected for seasons to come.
