Abstract
An outboard motor is mounted with a multiple-cylinder engine having cylinders to which intake air is distributed through the intake manifold unit of an intake unit, respectively. The intake manifold unit comprises an intake manifold body formed of a synthetic resin, an idling air control (IAC) valve for regulating a quantity of intake air into the intake manifold unit in an idling operation state, a valve holder to which the IAC valve is operatively connected in a floating manner, and an elastic member through which the IAC valve is mounted to the valve holder. The IAC valve, the elastic member and the valve holder are coupled integrally with each other and mounted to the intake manifold body in the floating state.
