Mercury – Fuel Pump Assembly | Fuel System Components | Marine-Grade Construction | 8M6010285

Overview

Every boater knows the quiet reassurance that comes from an engine that lights off smoothly and keeps on running without a hiccup. On the smaller outboards—where every pull, every squeeze of the throttle matters—that peace of mind starts with steady, reliable fuel delivery. The Quicksilver 8M6010285 Fuel Pump Assembly brings that confidence back to your classic 6–15 horsepower Evinrude or Johnson outboard. Whether you're creeping across a glassy lake at first light or running against a mid-afternoon breeze, this pump helps your motor breathe and respond the way it was meant to.

Performance & Practical Benefits

When a fuel pump starts to weaken on a small outboard, you feel it right away—sluggish starts, uneven idle, fading power when you try to open it up. Installing the Quicksilver 8M6010285 brings that crisp, steady response back. You’ll notice the difference the first time the engine fires on the first pull or settles into a smooth rhythm at idle.

Because it's built to match OEM specifications, the pump maintains the correct fuel pressure throughout the entire operating range. That steadiness translates directly into better throttle response and more predictable performance, especially when maneuvering in tight spots or moving through shallow water where control really matters.

Durability is also a key advantage. This pump is engineered to handle the vibration, heat, and fuel conditions that older two-strokes often experience. Once installed, it’s the kind of part you can trust for season after season with just basic routine maintenance.

Why Buy OEM

You can find cheaper alternatives, but with fuel delivery, accuracy and reliability matter far more than a small cost difference. An OEM-spec Quicksilver pump means proper fitment, correct pressure output, and long-term dependability. It’s built for the environment your outboard lives in, and it’s designed to install without chasing leaks or mismatched fittings. For small motors that you rely on for fishing trips, family outings, or tender duty, OEM-level quality is simply the smarter investment.
