ABSTRACT:
A cowling structure for a marine propulsion engine is disclosed which effectively prevents water from entering the air intake opening, while at the same time maintains optimum engine performance. The cowling structure has an engine cowl which encloses the engine and which defines an air intake opening. An air duct molding is associated with the engine cowl such that it extends over the air intake opening and, in conjunction with the engine cowl, defines an air inlet facing toward a rear portion of the cowling structure. A wall extends between the engine cowl and the air duct molding and is located between the air intake opening and the air inlet. Sidewalls, which are spaced apart a distance less than the width of the wall, direct any water entering the air inlet towards the wall to effectively prevent the water from entering the air intake opening.
