Performance & Real-World Benefits

The 807006 J-joint seal plays a quiet but vital role in keeping your Bravo drive running smoothly. Over time, seals can harden or crack, allowing small amounts of water or grit to sneak in — and that’s all it takes to start wearing down expensive internal parts.

This OEM replacement fits snugly, stays flexible, and maintains a perfect seal even when temperatures swing or vibration ramps up. Once installed, you’ll know your drive is properly sealed against leaks, helping your gears and bearings stay lubricated, cool, and corrosion-free for the long haul.

Why Choose Mercury OEM

Mercury doesn’t just build engines — they build systems designed to survive the marine environment. The Quicksilver 807006 seal is made from materials that handle pressure, oil exposure, and saltwater without breaking down. Aftermarket options might be cheaper, but they often use lower-quality rubber that doesn’t last as long or fit quite right.

With a genuine Mercury seal, you’re getting the same level of engineering and testing used on factory-new Bravo drives. It fits perfectly, seals completely, and performs exactly the way it should — every time you’re on the water.
