Yamaha - Throttle Body - Air Intake & Fuel Control - 6EM-13751-00-00

Overview

Throttle bodies are one of those components you really notice when they’re not right—rough idle, hesitation, or just a motor that doesn’t feel as responsive. After working on plenty of Yamaha setups, I’ve seen how a clean, properly functioning throttle body brings everything back into line. It controls how air moves into the engine, so it plays a big role in overall performance. When it’s dialed in, throttle response feels smooth and predictable every time you push forward.

Key Features

• Precise Airflow Regulation – Controls incoming air for balanced combustion and smooth engine response.
• Improved Throttle Response – Helps deliver consistent acceleration without hesitation.
• Integrated Sensor Compatibility – Designed to work seamlessly with Yamaha engine management systems.
• Durable Housing Construction – Built to handle heat, vibration, and constant airflow demands.
• Exact OEM Fitment – Matches factory specifications for proper alignment and sealing.

Engine & Boat Compatibility

Designed for Yamaha outboard engines equipped with electronic fuel injection systems requiring a throttle body assembly. Commonly used across a range of mid to high horsepower Yamaha outboards in recreational and commercial boats. Suitable for both freshwater and saltwater applications where consistent air intake control is essential.

FAQ

Q: What are signs the throttle body is going bad or dirty?
A: Rough idle, hesitation when accelerating, or inconsistent throttle response are common indicators.

Q: Does this need calibration after installation?
A: In most cases, the system will relearn, but it’s always a good idea to follow proper reset or relearn procedures if recommended.

Q: Any installation tips to keep in mind?
A: Make sure all connections are clean, especially sensors and gaskets, and double-check for air leaks.

Q: How does saltwater exposure affect this part?
A: Salt buildup can affect moving parts and sensors, so regular inspection and cleaning help prevent issues.

Q: Can a faulty throttle body affect fuel efficiency?
A: Yes, improper airflow can throw off the air-fuel mixture, which can impact both performance and fuel usage.
