Mercury – Magnesium Anode Kit | Bravo One Series | Magnesium Protection | 888757Q02

Overview

Every freshwater boater knows that long days on the lake can be hard on a sterndrive, even when the water looks calm and clean. Corrosion is slow, sneaky, and unforgiving—but with the right gear, it never has a chance to get started. The Quicksilver 888757Q02 Magnesium Anode Kit gives your MerCruiser Bravo One drive the kind of dependable protection you can feel good about each time you throttle up. It’s the quiet reassurance that your drive is shielded by components engineered specifically for the waters you run, letting you focus on smooth cruising, clean holeshots, and unhurried dockside evenings.

Performance & Practical Benefits

When anodes are doing their job, your drive simply feels better over time. The steering stays tight, the trim responds smoothly, and the mid-season inspection looks exactly how it should. Magnesium is the top choice for freshwater because it reacts quickly and pulls corrosion away from the components you need to protect.

The pieces in this kit fit cleanly, with no awkward adjustments or guesswork. Installation takes only basic tools, and once everything’s in place, the anodes go to work immediately. You’ll notice how simple it is to inspect them, too—one glance during routine maintenance tells you how they’re wearing. And because Quicksilver matches Mercury Marine’s exact engineering standards, the protection is even and predictable. That kind of steadiness pays off in smoother operation, longer component life, and fewer surprises when you haul out for the season.

Why Buy OEM

There’s a reason experienced boaters stick with genuine Quicksilver and Mercury Marine parts: they’re designed to do the job right the first time. Magnesium alloys that meet precise specifications react properly in freshwater, something many aftermarket anodes fail to match. Choosing OEM means choosing long-term reliability, consistent protection, and parts that install cleanly without improvisation. When you rely on your boat as much as you rely on your weekends, you want the kind of parts that keep things simple—predictable performance, straightforward upkeep, and real peace of mind.
