Before diving into the buying guide, it is essential to understand why an idle air control valve is crucial for your boat’s engine. The idle air control valve controls the amount of air that enters the engine while idling to maintain a proper air-fuel ratio. It ensures smooth idling and prevents stalling when your boat is in neutral or at low speeds.

Check Your Boat’s Compatibility
