Performance & Real-World Benefits

The 803098T1 repair kit is designed to stop leaks before they start. Over time, bellows and seals dry out or crack from constant heat, pressure, and water exposure. Replacing them with new OEM parts restores that tight, factory seal between the drive and transom.

This kit makes it easy to do the job right — everything fits perfectly, installs cleanly, and holds up under tough marine conditions. A proper reseal not only prevents leaks but helps your drive last longer, run smoother, and resist corrosion from the inside out.

Why Choose Mercury OEM

The Quicksilver 803098T1 is made by Mercury for Mercury — every part is engineered to match your sterndrive exactly. Aftermarket kits might look similar, but they often don’t fit perfectly or use cheaper materials that fail early.

Mercury’s OEM rubber compounds, clamps, and gaskets are designed for durability and a reliable seal that lasts through heat, saltwater, and vibration. It’s the same kit Mercury technicians use at the factory and in the field — proven to work and built to last.
