Yamaha - Throttle Body Assembly - Air Intake Control - 6CJ-13750-01-00

Overview

Throttle response is one of the first things you notice when running a Yamaha, and this assembly plays a big part in that. When everything is working right, the engine responds clean and steady from idle to full throttle. I’ve worked on motors that hesitated or surged, and it usually traced back to the throttle body. Swap in a solid assembly, and you get that smooth, predictable control back on the water.

Key Features

• Controlled Air Intake Flow – Regulates airflow into the engine for smooth and consistent throttle response.
• Responsive Throttle Operation – Helps eliminate hesitation and delivers steady acceleration.
• Durable Internal Construction – Built to handle constant movement, vibration, and engine conditions.
• Balanced Airflow Performance – Supports proper air and fuel mixture for efficient combustion.
• Factory-Spec Fitment – Designed to integrate seamlessly with Yamaha intake systems.

Engine & Boat Compatibility

Designed for Yamaha outboard engines utilizing throttle body intake systems. Suitable for a range of mid to high horsepower applications across recreational and performance marine setups.

FAQ

Q: What are signs a throttle body is failing?
A: Rough idle, hesitation when accelerating, or inconsistent throttle response are common signs.

Q: Can a dirty throttle body affect performance?
A: Yes, buildup can restrict airflow and cause poor engine performance.

Q: Does this need calibration after installation?
A: In some cases, yes—especially on electronically controlled systems to ensure proper response.

Q: Can I clean the throttle body instead of replacing it?
A: Minor buildup can be cleaned, but worn or damaged components should be replaced.

Q: Does saltwater use impact this part?
A: Over time, exposure can lead to corrosion or buildup if not properly maintained.
