Performance & Real-World Benefits

The 823912002 anode works quietly in the background, sacrificing itself to prevent corrosion on your outboard’s housing, bolts, and internal passages. Over time, it absorbs the electrochemical reactions that would otherwise attack your motor’s aluminum parts.

Installation is quick — just remove the worn anode and bolt the new one into place. Checking it regularly and replacing it when about half worn helps maintain full corrosion protection and saves you from expensive repairs down the line.

Why Choose OEM

Mercury’s OEM anodes are built with the exact aluminum blend required for consistent, balanced protection. Aftermarket versions may use cheaper alloys that corrode unevenly or fail to activate properly.

A genuine Quicksilver anode ensures proper fit, correct metal composition, and the kind of tested reliability Mercury owners trust.
