Abstract
An outboard motor includes an engine, a throttle valve connected to an inlet air silencer, and an intake manifold connected to a downstream portion of the throttle valve. A control valve is provided between a downstream portion of an intake passageway of the throttle valve and an upstream portion of the intake manifold, for controlling air supply in the low-speed driving of the engine. The control valve has a body formed with an intake passageway. The intake passageway of the body communicates in series with the intake passageway of the throttle valve.
