Mercury – Magnesium Anode Kit | Bravo II / Bravo III Series | Freshwater Protection | 888760Q03

Overview
If you spend your days cruising lakes or drifting quiet freshwater channels, you know how much depends on the hidden pieces of your sterndrive. It’s easy to forget about corrosion until it sneaks up on you, and by then the damage is already done. That’s why a good anode kit feels like insurance you can touch — a small, simple layer of protection that keeps the rest of your drive healthy. The Mercury Marine part number 888760Q03 Magnesium Anode Kit delivers that sense of security. It’s built for boaters who want their Bravo II or Bravo III drive to stay clean, strong, and dependable season after season, no matter how often the boat hits the water.

Performance & Practical Benefits
In real use, this kit does far more than just sit quietly under the surface. Magnesium offers the strongest corrosion protection in freshwater because it sacrifices itself before the aluminum housing of your sterndrive ever begins to wear. When these anodes are installed, you’ll notice the difference not in performance but in longevity — the drive stays cleaner, the hardware lasts longer, and you avoid the expensive surprises that show up when corrosion goes unchecked.

Everything fits with that tight, confident feel you expect from a Mercury Marine part. The anodes seat smoothly against the drive, the hardware installs without fuss, and once everything is in place, you have a complete, well-balanced layer of protection working for you every minute your boat is in the water. They’re easy to inspect, easy to replace, and they provide the kind of steady protection that makes maintenance feel simple instead of overwhelming.

For boaters who spend their time in lakes or rivers, this kit becomes one of the most practical investments you can make. Freshwater may look gentle, but it can be hard on metal — especially aluminum — and corrosion doesn’t take long to find its way in. With this OEM magnesium set, your sterndrive gets the shield it needs to stay strong and dependable.

Why Buy OEM
Anodes are one of those places where quality truly matters. A genuine Mercury Marine part ensures the material composition, fit, and protective performance meet the exact needs of your Bravo drive. Aftermarket anodes often use lower-grade metals or looser casting standards, causing them to wear too slowly (offering poor protection) or too fast (leading to waste and constant replacement). OEM means you’re choosing the right metal, the right shape, and the right level of protection — something every experienced boater will tell you is worth it.
