Performance & Real-World Benefits

When you’re running a Bravo drive, you rely on a sealed gear case to keep everything running smoothly. The 76868A04 kit restores that seal. Over time, old gaskets and O-rings can dry out or flatten, letting water seep in and contaminate the gear oil. This simple kit solves that — restoring a clean, tight seal that keeps moisture out and lubrication in.

It’s a smart bit of maintenance that saves you from much bigger headaches later. A clean, sealed drive runs quieter, lasts longer, and keeps you on the water instead of stuck in the shop.

Why Choose Mercury OEM

The Quicksilver 76868A04 is a factory-made Mercury kit, tested and approved for real marine use. Aftermarket seal kits might not fit perfectly or use the right rubber compounds, which can lead to early leaks or failure.

Mercury OEM seals are designed to match exact tolerances and materials, ensuring long-term reliability. You get the same precision and protection built into new Mercury drives — tested, proven, and trusted by boaters everywhere.
