ABSTRACT:
In an outboard motor air intake system, there are equipped with a secondary air passage connected to an air intake pipe at a location downstream of the throttle valve in terms of intake air flow; a manual valve installed in the secondary air passage to be operable by the operator to regulate a sectional area of the secondary air passage, a knob positioned at a location remote from the outboard motor to be operable by the operator, and a wire connecting the knob to the manual valve, such that the sectional area of the secondary air passage can be regulated through the knob and the manual valve at the location remote from the outboard motor, thereby making it easy to realize fine regulation when the engine operates in a low-speed such as idling.
