Yamaha - Carburetor Assembly 2 - Fuel and Air Delivery System - 69H-14902-04-00

Overview

When a Yamaha starts acting up at idle or feels off through the throttle, the carburetor is usually where I look first. This assembly controls how fuel and air mix, and when it’s right, the engine runs smooth and predictable. I’ve replaced a lot of worn carbs that brought motors back from rough running to steady and reliable. It’s one of those parts that makes a big difference in how the engine feels every time you head out.

Key Features

• Balanced Fuel and Air Mixing – Delivers the proper ratio for clean combustion and steady engine performance.
• Direct Yamaha Fitment – Designed to match factory specifications for easy installation and proper function.
• Durable Marine Construction – Built to handle fuel exposure, vibration, and harsh on-water conditions.
• Consistent Idle and Throttle Response – Helps eliminate hesitation and keeps the engine running smoothly.

Engine & Boat Compatibility

Compatible with Yamaha outboard engines using carbureted fuel systems. Commonly used on small to mid-horsepower Yamaha motors across skiffs, utility boats, and general recreational applications.
