Mercury – Weber 4-Barrel Carburetor Repair Kit | Carburetion System | Precision Marine Components | 8M0120196

Overview

Anyone who has spent time with a classic MerCruiser 4.3LX knows how rewarding it is when the engine fires cleanly, settles into a steady idle, and responds the moment you lean into the throttle. But when a carburetor starts showing its age—maybe a stumble on acceleration, a rough idle, or a bit of hesitation—you feel it right away. That’s when a proper rebuild becomes less of a chore and more of an investment in smoother days on the water.

The Quicksilver 8M0120196 Weber 4-Barrel Carburetor Repair Kit brings that sense of confidence back. It’s everything you need in one box, made to restore the crisp, dependable feel these engines had from the factory. And once the work is done, you’ll hear it—and feel it—the moment the engine settles into that smooth, steady rhythm you’ve been missing.

Performance & Practical Benefits

A well-maintained carburetor completely changes how your boat handles. With fresh gaskets sealing tight, the engine breathes correctly again. The new accelerator pump delivers crisp throttle response, while the updated needle and seat help fuel flow stay consistent—even when the water gets choppy.

Once installed, the difference is immediate. The engine idles more smoothly, warms up with less fuss, and responds with a clean push when you throttle up to get on plane. That sluggish hesitation you may have gotten used to? Gone. Instead, you get a steadier, more predictable ride that makes docking easier and cruising more enjoyable.

It’s practical peace of mind—the kind you appreciate most when you’re miles from the dock and just want your boat to run the way it should.
