Mercury – Weber 4-Barrel Carburetor Repair Kit | Carburetion System | Precision Marine Components | 8M0120197

Overview

There’s something familiar and almost comforting about the way a MerCruiser 4.3LH or LXH engine sounds when it’s running the way it should. The steady rumble at idle, the smooth pull onto plane, the consistent power when you’re carving through open water—those moments remind you why you love boating in the first place. But when a carburetor starts to wear out, the signs creep in slowly: a stumble here, a hard start there, maybe a little hesitation that wasn’t there before.

The Quicksilver 8M0120197 Weber 4-Barrel Carburetor Repair Kit brings that reliability back. It’s designed to restore the heart of your fuel system so your engine can breathe and respond the way Mercury intended. Once the rebuild is done, you’ll notice the difference immediately. The engine settles into a smoother rhythm, throttle response tightens up, and the whole boat feels more predictable and enjoyable.

Performance & Practical Benefits

A fresh carburetor rebuild does more than solve a single problem—it transforms the overall feel of your boat. With the new gaskets sealing cleanly and the accelerator pump back to full strength, fuel delivery becomes smoother and more precise. The inlet needle and seat help stabilize fuel flow, even when the water is rough or you’re constantly throttling up and down.

After installing the kit, you’ll feel the engine respond more predictably. Cold starts become easier. Idle steadies out. Getting on plane takes less effort. Even slow-speed maneuvering—those tight slips and no-wake zones—feels more controlled. It’s the kind of improvement that seasoned boaters notice right away because the boat simply behaves better.

Durability matters too. Every component in this kit is designed to withstand the harsh, wet, unpredictable conditions marine engines face. That means fewer headaches and more time spent enjoying the water.

• A precise fit engineered specifically for your engine.
• Long-term reliability, season after season.
• Materials tested to hold up in real marine environments.

It’s the same advice you’d give a buddy at the marina—use the part that was designed for the job.
