Performance & Practical Benefits

When you slide this bellows into place, you’ll feel the kind of fit that makes everything about your sterndrive system work smoother. The rubber flexes just enough to handle vibration and movement without losing its seal, keeping exhaust flowing exactly where it should. That steady routing has a noticeable impact on how cleanly your engine breathes, especially at idle or low speeds.

Durability is where this Mercury Marine part really stands out. The rubber is tough without feeling rigid, and you can tell it’s built to handle years of exposure to heat, water, and the constant motion of the drive. The Stainless Steel clamps bite down firmly, giving you a tight, dependable hold that won’t loosen the first time the water gets rough. Installation is straightforward — the kind of job many boaters knock out on a weekend afternoon, knowing they’re setting themselves up for fewer headaches down the line.

Why Buy OEM

When you’re dealing with sterndrive components, especially those responsible for sealing exhaust pathways, it’s worth sticking with genuine Mercury Marine parts. They’re built for exact fitment, meaning you won’t have to wrestle with alignment or worry about a loose connection. Aftermarket versions may look similar, but they often lack the long-term resilience and flexibility that matter most once the engine heats up and the drive starts moving. Choosing this Mercury Marine part number is simply the practical choice — the one that keeps your system running smooth and saves you trouble in the long run. It’s the kind of advice seasoned boat owners pass along because it’s rooted in real experience, not guesswork.
