Overview

There’s something reassuring about launching your boat and knowing the gear beneath the surface is protected. Your Bravo III drive works hard every time you push away from the dock, and corrosion is always waiting for a chance to take its toll. The Mercury Marine part number 888761Q04 Aluminum Anode Kit gives your drive the protection it deserves, whether you’re cruising a freshwater lake at sunrise or carving through salty coastal chop in the afternoon. It’s a simple but essential layer of defense — one of those small things that keeps the big things running smoothly.

Performance & Practical Benefits

When it comes to marine corrosion, prevention is everything. Once installed, the 888761Q04 anodes begin acting as a sacrificial shield, drawing galvanic activity away from your Bravo III’s aluminum housing and hardware. That means smoother seasonal maintenance, less pitting, and a drive that stays strong and dependable through every launch and every haul-out.

Aluminum anodes have become a favorite among modern boaters because they deliver consistent performance in both saltwater and freshwater environments. They tend to last longer than zinc, wear more evenly, and offer reliable protection in mixed water conditions — perfect for boaters who travel between lakes, rivers, and coastal bays.

Installation is straightforward, and everything fits with the tight, secure feel Mercury parts are known for. Clean mating surfaces, proper hardware, and anodes that sit exactly where they should — that’s what ensures the system works the way it’s engineered to. Once installed, inspection is quick and replacement is simple, giving you an easy long-term maintenance rhythm.

For anyone who keeps their boat in the water for extended periods, this anode kit becomes even more essential. Day after day, the anodes quietly do their job, taking the hit so your sterndrive doesn’t have to.

Why Buy OEM

When it comes to anodes, quality is more than a buzzword — it’s chemistry. A genuine Mercury Marine part guarantees the correct aluminum alloy composition, ensuring each anode sacrifices itself at the proper rate to protect your Bravo III. Aftermarket versions often vary in purity or casting quality, which can lead to uneven wear or poor protection. OEM parts eliminate that uncertainty. They’re engineered, tested, and proven to deliver exactly the protection your drive requires.
