ABSTRACT:
In An outboard motor mounted on a stem of a boat and having an internal combustion engine, a throttle body (that accommodates the throttle valve) is installed at a position close to the boat, and an electric motor is fastened to the throttle body so as to drive the throttle valve to open or close through a simple gear mechanism. This arrangement can mitigate operation load and offer improved operation feel. Further, it is simpler than a cable or a link mechanism, does not lead to an increase in number of components or weight, and hence the amount of required installation space can be reduced. A knob is provided and the operator can pinch and rotate it to open the throttle valve manually, when the electric motor breaks down.
