Performance & Real-World Benefits

The 823912 aluminum anode kit acts as a shield for your outboard, absorbing corrosion before it can reach vital components like your gearcase and mounting hardware. The aluminum alloy provides reliable protection in any water type — salt, fresh, or brackish.

Replacing your anodes regularly is quick and inexpensive but prevents expensive damage later. Just inspect them a few times per season and swap them out when you see pitting or heavy wear.

Why Choose OEM

Mercury’s OEM anodes are precision-cast to fit perfectly and provide even, consistent protection across your outboard’s metal surfaces. Aftermarket anodes might not match Mercury’s exact alloy blend, which can cause uneven wear or weak protection.

A genuine Quicksilver anode kit guarantees the right fit, correct composition, and dependable corrosion defense — the same quality Mercury installs at the factory.
