Mercury – Quicksilver Carburetor Gasket Kit | Fuel System Rebuild Kit | V6 2-Stroke Outboards | 6452

Overview

A good seal is the difference between a smooth-running outboard and one that stumbles. The Mercury Marine 6452 Quicksilver Carburetor Gasket Kit gives your Mercury or Mariner 135–200HP V6 2-stroke outboard the fresh seals it needs for reliable performance. Old gaskets dry out, shrink, or crack over time, letting air and fuel mix unevenly. This OEM kit includes everything — gaskets, seals, and a few key hardware pieces — to bring your carburetor back to tight, factory-fresh condition.

Key Features

Performance & Real-World Benefits

The 6452 gasket kit helps your carburetor breathe right again. With new seals in place, the engine draws fuel and air evenly, giving you quicker starts, steadier idle, and better mid-range punch. Each gasket is cut from material that won’t swell or soften when exposed to modern fuels, so the seal stays tight season after season.

Replacing old gaskets also prevents fuel seepage and protects against corrosion inside the carburetor body. A simple rebuild with this kit can make your engine feel years younger.

Why Choose Mercury OEM

The Quicksilver 6452 is a factory Mercury kit, built specifically for V6 2-stroke carbureted engines. Generic gasket sets often use cheaper paper or rubber that breaks down fast in ethanol blends.

Mercury’s OEM kits use materials chosen to survive marine conditions — heat, vibration, and fuel exposure — while holding a perfect seal. Using genuine parts means your carburetor performs exactly like it did when new, with no leaks and no guesswork.
