Performance & Real-World Benefits

The 804844002 carburetor repair kit is the go-to fix for tired carburetors that no longer perform like they should. Over years of use, gaskets dry out, seals weaken, and fuel deposits build up, leading to inconsistent fuel delivery and poor throttle response. Rebuilding with this OEM kit restores proper fuel metering, smoother idling, and stronger acceleration — all while improving overall efficiency.

Each component is built to Mercury’s factory specs, using materials that resist ethanol and fuel varnish. Once rebuilt, your carburetor will run like new, helping your engine start easily and perform reliably whether you’re trolling at idle or running wide open.

Why Choose Mercury OEM

The Quicksilver 804844002 is a genuine Mercury Marine kit, engineered to deliver the same fit, finish, and reliability as the parts originally installed on your engine. Aftermarket kits often include mismatched components or cheaper materials that don’t seal as tightly or last as long.

Mercury’s OEM kits are tested to handle marine conditions — from humidity and vibration to modern fuel blends — ensuring every rebuild gives you lasting results. It’s the same kit used by Mercury technicians, trusted for decades to bring older MerCruiser engines back to their best.
