Performance & Real-World Benefits

A worn needle or seat can cause fuel to leak past the float, flooding your engine and making starts a chore. The 7824 assembly restores precise fuel control so your engine starts easily, idles smoothly, and runs clean at every throttle range.

Replacing it is quick and affordable — the kind of small maintenance step that can prevent bigger issues later. You’ll notice more stable RPMs, stronger throttle response, and less fuel smell or dripping from the carbs.

Why Choose Mercury OEM

The Quicksilver 7824 is a genuine Mercury Marine part, built to the same tolerances as the original carburetor components. Cheaper versions often fit loosely or use softer materials that wear quickly or corrode when exposed to modern fuels.

Mercury OEM parts are precision-tested for pressure control, flow consistency, and longevity in real marine environments. Using Mercury parts means your carburetor stays in tune and your outboard runs the way it was designed to.
