Mercury – Carburetor Repair Kit | FourStroke Series | Marine-Grade Components | 8M0044576

Overview

Every boater has had that moment—the engine hesitates just a little as you throttle up, and you immediately know something’s not quite right in the fuel system. On small outboards especially, a healthy carburetor makes all the difference between a smooth day on the water and fighting the motor at every turn. The Mercury Marine part number 8M0044576 Carburetor Repair Kit brings that confidence back. It’s the kit you reach for when you want your outboard to start clean, idle steady, and respond the way it should.

There’s something comforting about knowing you’ve refreshed the heart of your engine’s fuel delivery system with parts that fit exactly as intended. No guesswork, no hoping the aftermarket gasket is “close enough.” Just dependable components designed to bring your Mercury 8–9.9 horsepower FourStroke back to the crisp, responsive feel it had when it first hit the water.

Performance & Practical Benefits

A refreshed carburetor changes the entire personality of a small outboard. With this kit installed, you’ll notice the engine breathing easier, idling smoother, and responding more quickly when you push the throttle. The float and needle work together to keep fuel levels steady, and the new gaskets create the tight, reliable seal that prevents those frustrating hiccups or stumbles when shifting from idle to power.

The materials in this kit feel solid and intentional—nothing flimsy, nothing loosely cut. Each part drops into place without forcing or trimming, and once everything’s assembled, you’ll feel the difference immediately. Cold starts become more dependable. Transitions feel cleaner. And the overall rhythm of the engine settles into that steady, confident thrum you expect from a well-maintained Mercury outboard.

Why Buy OEM

When it comes to carburetor components, the details matter. Aftermarket parts often look similar, but they rarely match the exact tolerances Mercury designs its engines around. A float that’s a millimeter off or a gasket that doesn’t quite seal can turn a small issue into a long day on the water.

Choosing a genuine Mercury Marine part means:

• The materials resist swelling and breakdown from ethanol-blended fuels
• The components fit perfectly with no modifications
• You reduce long-term fuel issues and avoid repeat repairs
• Your outboard performs like it was engineered to perform

It’s practical, proven, and ultimately the most cost-effective way to keep your motor running strong.
