Abstract
An outboard motor comprises an engine mounted within an engine compartment. The engine comprises an induction system having an induction passage extending between an air intake box to a combustion chamber. A throttle valve is positioned along the passage. A bypass passage communicates with the passage at a location between the throttle valve and the combustion chamber. An adjustable valve controls flow through the bypass passage. The adjustable valve is opened as the throttle valve is opened or as the engine speed is increased. The adjustable valve is closed when the throttle valve is rapidly closed or when the engine speed is rapidly decreased.
