The throttle body controls how much air enters the engine, working together with the fuel injectors and engine control unit to maintain the correct air-fuel ratio across the entire RPM range. A throttle position sensor reports throttle angle to the ECU, and an idle air control (IAC) valve manages airflow at idle independent of throttle position, both critical inputs for smooth, stable engine operation.
Boat Max Online stocks genuine Suzuki OEM throttle body assemblies, intake manifolds, IAC valves, and throttle position sensors for the DF EFI outboard lineup. These components work in close coordination with the fuel injection system, and a fault in any one of them, a dirty throttle body, a failing IAC valve, can cause idle instability or hesitation even when the fuel system itself is functioning correctly.
As an authorized Suzuki Marine dealer, every throttle body and intake component we sell is genuine Suzuki product calibrated to work correctly with your engine's EFI system. Free shipping on orders over $499 to the lower 48 states.
