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

Overview

Throttle bodies are one of those parts you notice right away when something’s off—hesitation, rough idle, or just not getting clean response when you push the throttle. I’ve worked on enough Yamaha setups to know how much this piece affects how the engine feels overall. It controls how air comes in, which ties directly into performance and efficiency. When it’s right, everything feels smooth and predictable out on the water.

Key Features

• Controlled Air Intake Flow – Regulates incoming air for balanced combustion and smooth operation.
• Responsive Throttle Performance – Helps deliver clean acceleration without lag or hesitation.
• Integrated Sensor Compatibility – Designed to work with Yamaha engine management systems for accurate input.
• Durable Housing Construction – Built to handle heat, vibration, and continuous airflow demands.
• Precision Yamaha Fitment – Ensures proper alignment and sealing within the intake system.

Engine & Boat Compatibility

Designed for Yamaha outboard engines equipped with electronic fuel injection systems requiring a throttle body assembly. Commonly used across mid-range Yamaha outboards in recreational and commercial boats. Suitable for freshwater and saltwater environments where consistent air intake control is critical.

FAQ

Q: What are signs the throttle body is dirty or failing?
A: Rough idle, hesitation, or uneven throttle response are common signs.

Q: Does this part need calibration after installation?
A: In most cases, the system will relearn, but a reset procedure may be recommended depending on setup.

Q: Any tips for installing this throttle body?
A: Make sure all sensors and connections are clean and secure, and check for air leaks after install.

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 impact fuel economy?
A: Yes, improper airflow can disrupt the air-fuel mixture and reduce efficiency.
