Upper Exhaust Hose Bellows For Mercruiser 3.0 3.7 5.0 5.7L – Sierra 18-2762 / 70981A3 Replacement

If you're working on a Mercruiser stern drive—say a 3.0, 3.7, 5.0, or 5.7L—and you notice the exhaust bellows are looking cracked or just plain tired, this is the part you need.

It's the upper exhaust hose/bellows, made by GHmarine, and it crosses with a bunch of numbers: Mercruiser 70981A3, Sierra 18-2762, Mallory 9-72808, and GLM 89070.

So basically, it's a direct fit for a ton of applications.

It's brand new, still in the packaging, and comes with a 1-year warranty.

This is the hose that connects the exhaust outlet to the drive, keeping water out and letting exhaust flow right.

If you're doing a full bellows job or just replacing this one piece, grab this and get back on the water without worrying about leaks.
