Yamaha Reed Valve Assembly | Air Intake Component | 688-13610-00-00

Overview

Reed valves are one of those parts that make a big difference in how a two-stroke Yamaha feels on the water. When they’re worn or not sealing right, you’ll notice it fast—loss of power, rough running, and poor throttle response. This assembly helps keep airflow moving the way it should, giving the engine that crisp, responsive feel you expect. It’s a solid fix when performance starts slipping and you want to bring it back to life.

Key Features

• Controlled Airflow Intake – Regulates air movement into the engine for proper combustion.
• OEM Fitment – Matches Yamaha specifications for correct sealing and performance.
• Improved Throttle Response – Helps restore smooth and responsive acceleration.
• Reliable Construction – Built to handle repeated engine cycles and marine conditions.
