Performance & Real-World Benefits

The 806189Q1 aluminum anode quietly does its job so your drive doesn’t suffer. Positioned on the trim cylinder arms, it sacrifices itself to corrosion, protecting vital hardware and hydraulic components below the waterline. Over time, these anodes take the brunt of electrochemical wear — that’s their purpose.

Because they’re made from aluminum, they hold up longer than traditional zinc in both salt and freshwater environments. When installed, you’ll enjoy greater peace of mind knowing your trim system and lower drive components are protected from the kind of corrosion damage that can lead to costly repairs.

Why Choose Mercury OEM

The Quicksilver 806189Q1 is a genuine Mercury Marine product, not a generic knockoff. Aftermarket anodes can look similar, but their composition often varies, leading to uneven wear or incomplete protection.

Mercury’s OEM anodes are formulated to provide even, predictable corrosion control across the entire drive system. They’re tested to military-grade standards and designed specifically for MerCruiser drives. When you use Mercury OEM, you’re giving your boat the same protection it had when it left the factory.
