Yamaha - Float Chamber Gasket - Fuel System Sealing - 61A-14384-00-00

Overview

Anytime you open up a carburetor, that gasket is one of the first things I plan on replacing. It’s what keeps the float chamber sealed, and once it gets worn or brittle, you’re dealing with leaks or air getting where it shouldn’t. I’ve seen engines run rough just from a bad seal here. It’s a simple part, but it makes a big difference in keeping the carb working the way it should.

Key Features

• Leak Prevention Seal – Keeps fuel contained within the float chamber to prevent seepage.
• Fuel-Resistant Material – Built to handle constant exposure to gasoline without breaking down.
• Precision Cut Design – Matches factory shape for proper sealing and alignment.
• Essential Rebuild Component – Ideal for use during carburetor service or maintenance.
• Maintains Stable Operation – Helps support consistent fuel delivery and smooth engine performance.

Engine & Boat Compatibility

Designed for Yamaha outboard engines with carbureted fuel systems. Commonly used on small to mid-range horsepower outboards found on fishing boats, skiffs, and utility vessels. Always confirm compatibility with your specific engine model.
