Mercury – Quicksilver Aluminum Anode Kit | Sterndrive Corrosion Protection Series | Aluminum Finish | 8M6007991

Every boater knows corrosion is always lurking below the surface. You may not see it day to day, but the water, the current, and the metals beneath your boat are constantly interacting. When you have a good anode kit in place, there’s a quiet confidence that settles in — the kind that lets you focus on the run ahead instead of worrying about what’s happening under the waterline.

Performance & Practical Benefits

This anode kit brings protection you can actually feel over time — not in the moment, but in the seasons that follow. Cast aluminum offers superior performance in both fresh and saltwater, reacting efficiently to shield the more critical metals on your drive. Instead of corrosion eating away at your sterndrive housing, hardware, and props, the anodes take the impact, wearing down gradually as they’re meant to.

Installation is smooth and straightforward. Each anode fits securely, aligning cleanly with the Volvo two hundred ninety Duoprop mounting points. The included Stainless Steel hardware makes the entire process feel solid and dependable. Once installed, everything sits tight and steady, ready to defend your drive every time you power up and push away from the dock.

Over the course of a boating season, you’ll notice how predictable the maintenance becomes. A quick inspection tells you exactly what’s happening. If you see pitting or deep wear, you replace the anodes and continue enjoying reliable protection. That consistency adds up to real savings — fewer repairs, longer sterndrive life, and more time on the water with equipment you can trust.

Why Buy OEM

A genuine Mercury Marine part means you’re relying on engineering built specifically for marine conditions, not a generic aftermarket blend. With OEM, the aluminum formulation, fitment, and durability are all controlled with precision. You get a kit that lasts, performs, and matches your sterndrive exactly as intended. Aftermarket options may cost less upfront, but they often fall short in protection and longevity — two things that matter deeply when your equipment is submerged in unpredictable conditions. Choosing OEM is simply the smarter, long-term choice for any boater who values reliability.
