Yamaha - Throttle Body 1 - Intake System Component - 68V-13751-20-00

Overview

The throttle body is a key component of your Yamaha outboard’s intake system, responsible for controlling the amount of air entering the engine during operation. By regulating airflow based on throttle input, it plays a critical role in maintaining proper air-to-fuel balance for efficient combustion. A worn or malfunctioning throttle body can lead to rough idle, hesitation, or reduced engine performance. Replacing it helps restore smooth acceleration, consistent idle, and reliable overall engine response.
