ABSTRACT:
An intake duct for an outboard engine. A cowling atop the engine forms, with a top cover plate, a recess which opens rearwardly. Intake parts are formed at the right and left sides of this recess, near the upper elevation thereof, in the vicinity of the cover plate. This provides for air flow in such a way as tends to remove, in the recess, water which is entrained in the air stream, before the air flows out of the intake ports to the engine.
