Yamaha - Float Chamber Gasket - Carburetor Seal - 63V-14984-00-00

Overview

This gasket might be small, but it’s one of the first things I check when a carb starts leaking or acting up. I’ve seen engines run rough just because the float bowl wasn’t sealing tight anymore. It keeps fuel where it belongs and helps the carb do its job consistently. When it’s fresh and sealing right, you don’t have to worry about leaks or uneven performance.

Key Features

• Fuel Bowl Sealing – Creates a tight seal between the carburetor body and float chamber.
• OEM Fitment – Designed to Yamaha specifications for proper alignment and sealing.
• Leak Prevention Design – Helps stop fuel seepage and maintain proper carb function.
• Fuel-Resistant Material – Built to withstand constant exposure to gasoline.

Engine & Boat Compatibility

Fits Yamaha outboard engines equipped with carbureted fuel systems. Commonly used on small- to mid-range horsepower outboards across fishing boats, tenders, and recreational vessels.
