Yamaha - Carburetor Float - Fuel Level Control - 6H4-14985-01-00

Overview

When a carburetor isn’t holding a steady fuel level, everything else starts acting up. I’ve worked on engines that flooded out or ran lean just because the float wasn’t doing its job anymore. It’s a simple part, but it controls how much fuel sits in the bowl at any given time. Get that right, and the motor runs smooth and predictable again.

Key Features

• Fuel Level Regulation – Maintains the correct fuel level inside the carburetor for proper operation.
• Balanced Float Design – Helps ensure consistent fuel delivery across idle and throttle ranges.
• OEM Precision Fit – Built to Yamaha specifications for accurate movement and sealing.
• Lightweight Construction – Designed to respond quickly to fuel level changes without sticking.
• Supports Smooth Operation – Helps eliminate flooding, hesitation, and uneven engine performance.

Engine & Boat Compatibility

Designed for Yamaha outboards equipped with compatible carbureted fuel systems. Commonly used on small to mid-size engines found on fishing boats, skiffs, and recreational vessels. Always verify compatibility with your specific engine before installation.
