Sierra 18-60151-9 Zinc Anode, Replaces 55989A3/55989Q9/55989T9, Alpha One SS 1982-89, Pack of 10

The Sierra 18-60151-9 is a zinc sacrificial anode built to protect Mercruiser sterndrive components from galvanic corrosion. Zinc anodes work by corroding preferentially to the surrounding metal, so critical drive components stay protected as long as the anode is intact and making good electrical contact. This listing is priced per package of 10 anodes, making it an economical way to stock up for routine replacement, since anodes are a wear item that should be inspected regularly and replaced once significantly eroded.

The Sierra 18-60151-9 is designed for use on Alpha One SS (1982-89) applications and is a direct cross-reference for the Mercruiser 55989 series of anodes. It is manufactured from zinc for reliable sacrificial corrosion protection and is built to meet or exceed the performance of the original equipment part it replaces.
