Mercury – Magnesium Anode Kit | Bravo III Series | Freshwater Protection | 888760Q04

Overview
When you spend most of your time on freshwater lakes, you get to know the quiet ways your boat talks to you. A smooth tilt, a clean trim response, and a sterndrive that looks as solid as the day you bought it — those little things give you confidence every time you launch. The Mercury Marine part number 888760Q04 Magnesium Anode Kit helps preserve that confidence. It works in the background, guarding your Bravo III drive from the kind of corrosion you rarely notice until it’s too late. It’s simple insurance, built into the metal, and it lets you focus on the good stuff: glassy mornings, idle-speed coves, and long, slow dockside evenings.

Performance & Practical Benefits
A good anode set isn’t something you think about often — and honestly, that’s the point. Once installed, these magnesium anodes begin quietly absorbing the harsh electrical activity that naturally occurs underwater. Instead of your drive housing taking the hit, the anodes do. They’re the first line of sacrifice, protecting the pieces of your Bravo III drive that matter most.

With the 888760Q04 kit, you’ll notice how everything fits tightly and securely. There’s no rattling, no awkward alignment, no guessing whether the hardware is right. Every component feels like it belongs because it does. This is a kit engineered exactly for your drive series, so the installation is smooth and the protection starts the moment the boat touches the water.

In real-world terms, this means fewer corrosion surprises when you haul out at the end of the season. You’ll see even, predictable wear on the anodes rather than pitting on the drive. It means reduced maintenance costs over time and better long-term health for your sterndrive — something every freshwater boater appreciates, especially if you keep your boat in the water for long stretches.

Why Buy OEM
Anodes look simple, but the metal composition behind them is anything but. A genuine Mercury Marine part ensures every piece is cast to the right purity level and meets the exact sacrificial rate your Bravo III drive needs. Aftermarket anodes may look identical, but small differences in magnesium quality can dramatically reduce protection — or worse, offer none at all. With OEM, you’re getting protection designed by the same engineers who built the drive itself. It’s dependable, proven, and absolutely worth it.
