If you spend your weekends on freshwater lakes, you already know how quietly corrosion can sneak up on a good sterndrive. It’s the sort of problem you do not feel until it’s too late—unless you outfit your drive with the right protection. The Mercury 888757K01 Magnesium Anode Kit offers that steady, dependable layer of defense that seasoned boaters have learned to trust.

Performance & Practical Benefits

A well-protected Bravo One drive just feels better on the water. The steering remains tight and predictable, trim response stays smooth, and the drive housing maintains its strength season after season. That difference begins with proper anode protection. Magnesium anodes wear at a steady, controlled pace, pulling corrosion away from the components that matter most.

Installation is straightforward—each piece seats cleanly, and the included hardware makes the process more “Saturday morning tune-up” than “full afternoon overhaul.” Once installed, the kit quietly takes on the harsh chemical reactions in freshwater that would otherwise attack metal surfaces. You’ll appreciate how easy they are to inspect, too. A quick glance during routine maintenance tells you exactly when it’s time to replace them, keeping your upkeep simple and predictable.

Why Buy OEM

There’s a reason boaters stick with genuine Mercury Marine parts: they’re built to fit right and perform right the first time. This magnesium anode kit uses alloys tested specifically for Bravo One environments, ensuring the correct wear pattern and protection levels. Aftermarket parts may look similar, but they rarely match the precision and long-term value of OEM components. When you choose Mercury, you’re choosing reliability, protection, and the peace of mind that comes from installing something engineered for your exact drive—not a compromise.
