Yamaha - Throttle Body 1 - Air Intake Control Component - 63P-13751-01-00

Overview

Throttle response is one of the first things you notice when something’s off, and a worn throttle body can throw everything out of sync. I’ve worked on setups where the engine hesitated or didn’t respond cleanly, and it traced back to wear or buildup right here. This component controls how air flows into the engine, which directly affects performance. When it’s clean and functioning right, throttle input feels smooth and predictable.

Key Features

• Airflow Control Housing – Regulates incoming air for proper engine combustion.
• OEM Fitment – Designed to Yamaha specifications for precise alignment and operation.
• Smooth Throttle Response – Supports consistent and responsive acceleration.
• Durable Construction – Built to withstand heat, vibration, and marine conditions.

Engine & Boat Compatibility

Fits Yamaha outboard engines equipped with compatible throttle and air intake systems. Commonly used across mid-range horsepower outboards on center consoles, bay boats, and recreational vessels.
