Quicksilver – Aluminum Prop Nut Anode Kit | Bravo Three Series | Cast Aluminum Finish | 865182Q01

Overview

There’s a certain kind of peace you feel when you know your sterndrive is protected — not hoped-for, not “good enough,” but truly protected. Corrosion can sneak up on even the most seasoned boater, and when it does, it’s usually the small, unseen spots that take the biggest hit. That’s why a good anode gives you real confidence. This Mercury Marine part is the kind of simple, dependable protection you appreciate every time you trim the drive up at the end of a long day. It’s solid, it fits right, and it does its job quietly so you can focus on the water instead of worrying about what’s happening beneath it.

Performance & Practical Benefits

When you hold this anode in your hand, you can feel its purpose — dense, rugged, and ready to sacrifice itself before corrosion touches anything more expensive. Aluminum anodes offer stronger and longer-lasting protection than traditional zinc, especially for boats that jump between freshwater and saltwater. They activate quickly and stay effective across a wide range of conditions.

Once installed, the anode forms a tight, secure connection around the prop shaft assembly. You’ll notice its clean fit immediately — no wobble, no awkward alignment, no forcing hardware into place. The Stainless Steel bolt gives the whole assembly a solid, confident feel that holds up to vibration and long seasons of use.

On the water, this anode works silently. It shields the drive housing, prop shaft, and surrounding components from galvanic corrosion — the kind that creeps in when dissimilar metals and stray electrical currents mix. That kind of protection extends the life of your Bravo Three drive dramatically. Over time, you’ll see the anode take the wear while the drive remains clean, smooth, and structurally sound. That’s exactly what you want.

Inspecting and replacing the anode is just as easy. A quick glance during haul-out or at the dock tells you how much life is left. And when it’s time to replace it, you’ll appreciate how the OEM shaping makes the job simple with just basic hand tools.

Why Buy OEM

When it comes to corrosion protection, guessing is expensive. Aftermarket anodes may not meet military specifications, may use inconsistent aluminum blends, or may not fit the Bravo Three prop nut assembly cleanly enough to function properly. That’s a risk no boater should take.

A Mercury Marine part gives you precise fitment, proper material quality, and predictable performance. You get the same engineering that Mercury builds into every Bravo Series drive — real, tested, proven protection. It’s the smarter, longer-lasting choice for anyone who wants to protect a major investment.
