Mercury – Magnesium Bracket Anode | Corrosion Protection | Magnesium | 8M0179705

Overview

Anyone who spends time on freshwater knows that corrosion doesn’t show up overnight. It sneaks in slowly—season after season—unless you’re ahead of it with the right protection. That’s why the magnesium bracket anode is one of those small, quiet heroes on your Mercury V12. You install it, forget about it, and it just works. With Mercury Marine part 8M0179705, you get that easy confidence every time you ease away from the dock or push the throttle for a long run across smooth morning water. It’s a simple component, but when you’re protecting a powerhouse like a V12 Verado or SeaPro, simple matters.

Performance & Practical Benefits

This magnesium bracket anode does something that most boaters never see firsthand—but the impact is huge. It absorbs corrosive activity before it can reach the expensive and vulnerable parts of your V12’s bracket and surrounding hardware. The result is a cleaner engine exterior, better long-term performance, and fewer surprises during routine service.

Magnesium is the right material for freshwater protection. It reacts quickly enough to shield the engine without wearing unevenly or failing prematurely. That means you get steady, predictable protection throughout the season. And because this is a genuine Mercury Marine part, the fit is tight, the alignment is correct, and the mounting surfaces match exactly. The anode stays where it should, works like it should, and protects what matters most—your investment in a premium outboard.

Why Buy OEM

When you’re protecting a V12 outboard, “close enough” isn’t good enough. Aftermarket anodes often use inconsistent alloys or off-spec dimensions, which can leave parts of your engine exposed. Mercury’s OEM 8M0179705 bracket anode is engineered, tested, and built to meet strict corrosion-protection standards. You get reliable wear patterns, proven material quality, and guaranteed fitment. It’s a small investment that saves you money and trouble down the line, and it’s exactly what Mercury designed your engine to run with.
