Mercury – Aluminum Anode Kit | MerCruiser Bravo One Series | Aluminum Construction | 888758K01

Overview

If you’ve owned a sterndrive long enough, you’ve seen what corrosion can do when it’s left unchecked. It starts small—just a little roughness here, a bit of pitting there—then one day you’re staring at metal that used to be smooth and solid. That’s why anodes are one of those parts I never treat as optional. They’re the quiet guardians of your drive, taking the hit so the expensive stuff doesn’t have to.

This Mercury Marine part is the kind of kit you put on and feel good about right away. Not because it’s flashy, but because it’s practical. You’re protecting your MerCruiser Bravo One the smart way, whether you boat in freshwater, saltwater, or bounce between both.

Performance & Practical Benefits

A good anode kit doesn’t make your boat faster, but it makes boating less stressful. With the right anodes in place, you’re actively steering corrosion away from the drive components you actually need to last. This kit spreads that protection across key contact points, so it feels like you’ve covered the whole system instead of just “doing one piece.”

In practical terms, it’s peace of mind at the dock and on the water. The fit is made for the Bravo One, so the parts sit the way they should and install without the awkward grinding, forcing, or guessing that can come with mismatched aftermarket kits. Once installed, everything feels secure and tidy. Then you get to move on with your season—less worrying about what’s happening under the swim platform.

Maintenance stays simple, too. You inspect periodically, and when the anodes show real wear or pitting, you swap them. That’s the whole point: predictable, controlled sacrifice that helps prevent unpredictable, expensive damage.

Why Buy OEM

Here’s the advice I’d give a buddy at the ramp: don’t gamble on corrosion protection. A genuine Mercury Marine part is designed around the Bravo One sterndrive’s dimensions and mounting points, so you’re not chasing fitment issues or wondering if the alloy is right for your water. OEM anodes tend to wear more consistently, install more cleanly, and deliver the kind of long-term reliability that makes the purchase worth it.

Over time, this is one of the most cost-effective ways to protect a sterndrive. Anodes are cheap compared to drive repairs, and getting the right kit the first time saves you time, frustration, and repeat orders.
