Mercury – Transom Seal Repair Kit | Sterndrives | 8M0095485

Overview

If you’ve had a Bravo or Blackhawk drive long enough, you already know the bellows and seals don’t stay perfect forever. They sit right where the heat, vibration, and movement all meet, so sooner or later they start cracking or letting a little moisture sneak in. This kit gives you everything you need to reseal the transom opening properly—new bellows, clamps, fittings, gaskets, the whole stack. It’s not the flashiest job, but it’s one of those repairs that keeps bigger problems from creeping up on you.

Performance & Practical Benefits

Once the new bellows and seals are in place, the boat usually tells you right away—less water in the bilge, smoother trim, and the exhaust sounds the way it should again. You’re also keeping the gimbal bearing and U-joints safe from water intrusion, which is a big win because those parts don’t tolerate moisture at all. A solid reseal brings back that “tight” feeling in the stern that tells you things are right.

Why Buy OEM

OEM bellows stretch and seal the way Mercury designed them to. Aftermarket versions can feel stiff or thin, and if a bellows fails early, you’re doing the whole job again. With OEM, the fit is dependable, and the materials last through real seasons on the water—not just bench tests.

FAQ

Q1: How do I know my transom bellows are on their way out?
A: Cracks, water showing up in the bilge, exhaust sounding different, or the drive feeling rough when trimming.

Q2: Can I do this job myself?
A: Some boaters do, but it’s tight work. A lot of folks let a shop handle it.

Q3: Should I replace all the bellows at once?
A: Yes—if one is failing, the others aren’t far behind.

Q4: What’s the risk of putting it off?
A: Water can ruin the gimbal bearing and U-joints fast, and that gets expensive.

Q5: How long do good bellows usually last?
A: A few seasons, depending on sun exposure and how often the boat’s used.
