ABSTRACT:
A unitary cowling assembly for covering a fore-to-aft extending marine propulsion engine comprising a front cowling section adapted to extend around a front portion of the marine propulsion engine and a rear cowling section adapted to be fixedly connected to the front cowling section and to extend around a rear portion of the marine propulsion engine is disclosed. By extending the front and rear cowling sections fore and aft of the engine and interconnecting the cowling sections along a stiffened joint that extends laterally across the engine, the top surface and the side surfaces of the cowling, which are subjected to the highest vibrational loads from operation of the marine engine, can be structurally reinforced so as to inhibit such vibrations and the associated noise, while still providing an easily moldable cowling assembly.
