Abstract
An intake duct for an outboard engine has a cowling, the upper rear portion of which has a recess that faces upwardly and backwardly. A cover plate covers the top of the recess so the recess opens rearwardly. Intake ports are formed at the right and left sides of the recess, near the upper elevation thereof, in the vicinity of the cover plate. At the front portion of the recess there is an annular wall which stands upright in the shape of a funnel to form an intake port that opens upwardly, facing the cover plate.
