Yamaha - Fuel Cock Assembly 1 - Fuel System Control - 61A-24500-00-00

Overview

The fuel cock is one of those small parts that makes a big difference when it’s working right—and a headache when it’s not. It controls fuel flow to the engine, so if it starts sticking or leaking, you’ll notice it pretty quickly. This is the kind of component I replace when fuel delivery feels inconsistent or hard to manage. Once it’s sorted, you get clean, controlled fuel flow and a lot more confidence running your setup.

Key Features

• Fuel Flow Control Valve – Regulates fuel supply to the engine for safe and consistent operation.
• Leak-Resistant Design – Helps prevent fuel seepage and unwanted air intrusion.
• Durable Construction – Built to handle fuel exposure and long-term marine use.
• Factory-Spec Fitment – Matches Yamaha design for proper installation and function.
• Smooth Operation – Allows easy switching between fuel positions without sticking.

Engine & Boat Compatibility

Designed for Yamaha outboard engines using manual fuel shut-off or selector valve 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 setup.
