Yamaha - Throttle Body 5 - Air Intake Control - 69J-13755-01-00

Overview

Throttle bodies are one of those parts you really feel when something’s off. On Yamaha engines, this piece controls how air flows into the motor, and that directly affects how smooth your throttle response is. When they start getting dirty or worn, you’ll notice hesitation or uneven power pretty quickly. A clean, properly working throttle body keeps everything crisp when you push the throttle forward.

Key Features

• Controlled Airflow Management – Regulates incoming air to maintain proper air and fuel balance across all speeds.
• Precision Yamaha Fitment – Built to match factory specs for proper alignment and smooth operation.
• Responsive Throttle Action – Supports clean acceleration and steady engine response under load.
• Durable Internal Construction – Designed to handle constant airflow, vibration, and engine heat.

Engine & Boat Compatibility

Compatible with Yamaha outboard engines equipped with electronic fuel injection systems that utilize multi-throttle body setups. Commonly found on mid- to high-horsepower Yamaha motors across a range of recreational and offshore boats.
