Performance & Practical Benefits

A fuel pump may be hidden under the cowl, but you feel its impact the second the key turns. With the Quicksilver 8M6010290, fuel delivery becomes tight, predictable, and remarkably smooth. Your throttle response improves, especially when jumping onto plane or pushing through chop. The engine idles more steadily, without that wandering, uneven rhythm that often hints at a weak or aging pump.

Because this is an electric pump built to precise OEM flow rates, your EFI system gets exactly the fuel volume it needs—no surging, no starving, no inconsistent pressure. The result is cleaner running, stronger mid-range pull, and better fuel atomization throughout the combustion cycle.

Installation is just as practical. The included hardware and gaskets help everything line up cleanly, reducing guesswork and making the job approachable even for an experienced do-it-yourself boater. Once installed, the pump delivers reliable performance season after season, even in demanding environments where heat, vibration, and ethanol exposure are daily realities.

Why Buy OEM

Boaters know fuel delivery isn’t the place to cut corners. Genuine Quicksilver parts give you:

• The exact pressure and volume your Yamaha EFI system was engineered for
• Long-term reliability under heat and vibration
• Proper fitment without modifying brackets or fuel lines
• Better engine longevity, stronger performance, and fewer breakdowns

Think of it as preventative peace of mind. A marine fuel pump has one job—do it right every time. OEM quality ensures that happens.
