Yamaha - Float Chamber Cover - Carburetor Component - 69J-14182-10-00

Overview

When you’re working on carbureted Yamaha setups, this is one of those small pieces that has to seal up right or you’ll be chasing fuel issues. A worn or warped float chamber cover can lead to leaks or inconsistent fuel levels, and that shows up fast when the motor’s running. I’ve swapped plenty of these out during rebuilds just to keep things clean and reliable. Once it’s seated properly, the carb does what it’s supposed to—no surprises.

Key Features

• Secure Fuel Chamber Seal – Keeps the float chamber properly enclosed to maintain consistent fuel levels.
• Precision-Machined Fit – Designed to align correctly with carburetor body and gasket surfaces.
• Corrosion-Resistant Material – Built to withstand fuel exposure and marine conditions.
• OEM Specification Design – Matches Yamaha tolerances for proper carburetor function.
• Stable Mounting Surface – Ensures even pressure across the gasket to prevent leaks.

Engine & Boat Compatibility

Compatible with Yamaha outboards using 69J-series carburetor and fuel system components. Commonly found in mid-range Yamaha outboards used in recreational and light commercial boating applications.
