Yamaha - Throttle Body 1 - Intake System Component - 68V-13751-10-00

Overview

The throttle body is a key part of your Yamaha outboard’s intake system, controlling how much air enters the engine based on throttle input. This precise airflow control is essential for proper combustion, smooth acceleration, and overall engine efficiency. If the throttle body becomes worn, dirty, or damaged, it can lead to rough idle, hesitation, or poor performance. Replacing it helps restore proper airflow and ensures your engine responds consistently and reliably.
