Performance & Real-World Benefits

A bad fuel connection can ruin a good day on the water. The 804786Q Quicksilver connector takes that worry off your mind. It’s built to deliver a solid connection that stands up to the pounding and vibration that come with real-world boating. Once it’s in place, it seals tight — no fuel drips, no air leaks, and no interruptions in engine performance.

Why Choose Mercury OEM

This isn’t just another hardware-store fitting — the Quicksilver 804786Q is a factory-engineered Mercury Marine part. Each one is tested to withstand the pressure, fuel flow, and corrosion challenges of real marine use. Cheap aftermarket parts might look close, but they rarely hold the same tight seal or stand up to long-term exposure to fuel and water.

Mercury’s OEM parts are made to do one thing: work flawlessly. When you install this connector, you know it fits right, seals tight, and won’t leave you stranded.
