Performance & Practical Benefits

When you pull your boat out for a midseason service, the last thing you want is a scavenger hunt for individual parts. This kit removes all that frustration. Each component is matched to your Bravo One drive, making installation smooth and predictable.

The O-ring kit ensures tight, confident sealing where it matters most. No surprises, no seepage—just that reassuring “set” you feel when parts fit the way they were designed to. The aluminum anodes quietly do their job every time your boat touches the water, guarding the drive against corrosion to protect performance and longevity. And the gearcase drain seals make your lube change straightforward, helping maintain crisp shifting and the steady, clean gear engagement that Bravo One owners appreciate.

When everything’s buttoned up, you’ll feel the difference: quieter transitions, smoother running, and a sterndrive that feels ready for whatever the day brings.

Why Buy OEM

Choosing OEM isn’t about being fancy—it’s about avoiding headaches. Mercury designs each part to work perfectly with the Bravo One system, and that level of engineering shows up in reliability, ease of installation, and long-term protection. Aftermarket parts might fit “well enough,” but in a marine environment, well enough usually turns into a problem down the road. With genuine Mercury components, you’re getting the right parts the first time, built to last and backed by decades of design and testing.
