Overview

Performance & Practical Benefits

Good anodes are the quiet heroes of any sterndrive setup. Once installed, the 888755K01 kit starts working immediately, absorbing the corrosion that would otherwise attack critical metal surfaces. That protection adds up to a drive that stays tight, smooth, and steady — the kind of feel you notice when you shift into gear or take a slow turn past the no-wake signs.

Magnesium anodes are the preferred choice in freshwater because they provide strong, efficient sacrificial action. You’ll be able to inspect them easily, spot wear clearly, and replace them at the right time. That rhythm of simple upkeep saves you headaches down the road and keeps your drive performing the way Mercury intended. And because this is a full kit, every vulnerable point is covered, from the lift rams to the bearing carrier.

Whether you’re docking at sunset or pulling skiers on a bright July morning, that quiet assurance that your drive is protected makes every trip a little better.

Why Buy OEM

Choosing a genuine Mercury Marine part means everything lines up the way it should. OEM magnesium anodes are cast to precise standards, allowing them to wear evenly and protect consistently. Aftermarket versions often cut corners on purity or machining, which can leave parts of your drive exposed. With OEM, you’re investing in longevity — the kind that saves you money, time, and stress over the lifespan of your boat. It installs right, performs right, and protects right from day one.
