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

Overview

When a Yamaha starts running rough or doesn’t hold a steady idle, the carburetor is usually the first place I check. This assembly controls how fuel and air mix, and when it’s right, the engine just runs smooth and consistent. I’ve replaced plenty of these on motors that were hard to start or bogging down, and the difference is immediate. It’s one of those parts that brings everything back into line.

• Direct Yamaha Fitment – Built to factory specifications for proper alignment and easy installation.
• Durable Marine Construction – Designed to withstand fuel exposure, vibration, and harsh marine environments.

Engine & Boat Compatibility

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