Yamaha Fuel Pump Repair Kit 63M-W2442-00-00 gives your outboard’s fuel system a quick reset without the cost of a full pump swap. Inside the box you’ll find everything that usually wears out first—fresh diaphragms, check-valve seals, and a stainless-steel spring—each built to Yamaha’s strict tolerances so pressure and flow return to factory specs. Install is straightforward: remove the pump cover, replace the old parts, torque to spec, and you’re back on the water before the ice in the cooler melts.
Why this kit belongs in your toolbox
- Complete refresh: new diaphragm, O-rings, and valves stop fuel leaks and cure hard-start issues.
- Marine-grade materials: Viton-blended rubber and stainless hardware shrug off salt, heat, and ethanol-blended fuels.
- Exact OEM fit: every gasket lines up perfectly with compatible Yamaha mid-range models—no trimming or improvising.
- Cost-saver: revives performance for a fraction of the price of a full assembly and extends overall pump life.
If you notice sputtering at throttle or sluggish acceleration, swap in the 63M-W2442-00-00 kit and let your Yamaha breathe right again—smooth, reliable, and ready for the next run.
