Lenco Sacrificial Anodes - 3-3/4" - 2 Pack

Lenco Sacrificial Anodes - 3-3/4" (2-Pack) are essential corrosion protection for any serious boater or angler who spends extended time on saltwater. After years running boats through challenging marine environments, protecting your engine, outdrive, and hull hardware from electrolytic corrosion isn't optional—it's maintenance you can't afford to skip.

These zinc-based anodes silently work to prevent costly damage to expensive marine equipment, extending the lifespan of critical components that would otherwise suffer rapid deterioration in saltwater conditions. The Lenco Sacrificial Anodes operate on a simple but proven principle: zinc is more electronegative than aluminum and steel, so it corrodes first instead of your equipment. Each 3-3/4" anode is engineered to provide robust protection across the components most vulnerable to galvanic corrosion—outdrives, trim tabs, thru-hull fittings, and cooling systems.

The 2-pack format gives you complete coverage or allows for strategic placement in high-risk areas where corrosion accelerates. Replacing these anodes annually or as they dissolve is far cheaper than replacing an outdrive or repairing corroded hardware mid-season. Saltwater anglers, commercial operators, and anyone running an inboard or outboard motor in coastal waters should stock these as part of routine seasonal maintenance.
