Mercury – Aluminum Anode | For MerCruiser Alpha One Gen II Drives | 806189T1

Overview

Corrosion is a constant battle for anyone running a sterndrive, and the Mercury 806189T1 Aluminum Anode is your front-line defense. Designed specifically for MerCruiser Alpha One Gen II drives, this small but important piece takes the damage so your engine doesn’t have to. It’s mounted on the trim cylinder arm or rod, where it absorbs corrosion before it can attack the metal parts that keep your boat moving. Built from marine-grade aluminum, it holds up in both fresh and saltwater and installs easily with the included hardware.

Performance & Real-World Benefits

The 806189T1 anode works quietly in the background, drawing the corrosion that would otherwise attack your drive’s internal parts. Over time, it sacrifices itself — that’s its job. It keeps your sterndrive housing, trim system, and other critical components safe from expensive corrosion damage.

Aluminum anodes last longer than zinc and offer better performance in both fresh and saltwater. Once installed, they require almost no attention beyond a quick visual check now and then. Replace them when you see significant pitting, and your drive will stay protected season after season.

Why Choose Mercury OEM

With the Mercury 806189T1, you’re getting the same level of protection that Mercury builds into every new drive. Aftermarket versions may look the same, but the metal composition isn’t always precise — and that can mean uneven wear or reduced protection.

Mercury’s OEM anodes are made from a proven aluminum alloy that’s tested to strict standards for corrosion control and lifespan. It’s the difference between hoping your drive is protected and knowing it is.
