Yamaha - Fuel Cock Assembly 1 - Fuel Control Valve - 6EE-F4500-00-00

Overview

Fuel cocks are one of those simple parts that you rely on more than you think, especially on smaller Yamaha setups. I’ve seen engines act up just because fuel wasn’t flowing cleanly through a worn valve. This is what lets you control fuel supply right at the source, whether you’re starting up or shutting things down. When it’s working right, fuel flow stays smooth and predictable every time you head out.

Key Features

• Manual Fuel Flow Control – Allows you to easily start or stop fuel supply to the engine.
• Consistent Fuel Delivery Support – Helps maintain steady flow for reliable engine operation.
• Durable Valve Construction – Built to handle fuel exposure and repeated use over time.
• Leak-Resistant Sealing Design – Reduces the risk of fuel leaks at the valve connection points.
• Direct Yamaha Fitment – Designed to match factory specifications for proper installation and function.

Engine & Boat Compatibility

Designed for Yamaha outboard engines requiring a manual fuel cock assembly within the fuel system. Commonly used on small to mid-range Yamaha outboards in portable and recreational boats. Suitable for freshwater and saltwater environments where reliable fuel control is essential.
