Yamaha - Throttle Body 3 - Air Intake Control - 69J-13753-01-00

Overview

When you’re dialing in a Yamaha motor, throttle bodies are a big part of how the engine feels on the water. This unit controls airflow into the engine, and if it’s not right, you’ll notice it in hesitation or uneven throttle response. I’ve seen engines smooth out instantly once a worn throttle body is replaced. It’s one of those parts that keeps everything feeling tight and responsive when you push it.

Key Features

• Precise Airflow Regulation – Controls incoming air to maintain proper air and fuel balance across the RPM range.
• Factory-Matched Fitment – Designed to align with Yamaha intake systems for proper sealing and operation.
• Smooth Throttle Response – Helps deliver consistent acceleration without lag or hesitation.
• Durable Internal Components – Built to withstand heat, vibration, and continuous engine use.

Engine & Boat Compatibility

Compatible with Yamaha outboard engines equipped with electronic fuel injection systems and multi-throttle body configurations. Commonly used across mid- to high-horsepower Yamaha motors on a wide range of boats, from inshore setups to offshore vessels.
