Performance & Real-World Benefits

The 803097T1 seal kit helps ensure your drive stays dry and protected from the inside out. Over time, old bellows and gaskets harden and crack, letting water seep into places it shouldn’t. Replacing them not only prevents leaks but also helps your drive run smoother and last longer.

This kit includes every seal and gasket needed for the upper housing — saving you time hunting for individual parts. Whether you’re doing a full service or just buttoning things back up after a rebuild, it’s an easy way to make sure everything seals properly the first time.

Why Choose Mercury OEM

The Quicksilver 803097T1 is built by Mercury, for Mercury. Every part is made to fit exactly the way the factory intended — no guessing, no trimming, no leaks. Aftermarket kits might save a few dollars up front, but the materials don’t always hold up to the heat and salt that marine drives face.

Mercury’s OEM seals and gaskets are designed to resist corrosion and maintain flexibility, giving you a tight, lasting seal. It’s the same hardware Mercury technicians use when servicing drives in the field, trusted for its durability and precision fit.
