Abstract

The marine propulsion device includes a lower unit which has a gear case 16 normally submerged in water and which is arranged to discharge engine exhaust gases through the propeller hub 54, the leading end of the gear case 16 having a tapered nose 18 and a trailing end of the gear case having a generally circular cross section and terminating in a generally vertical trailing edge 21 located forwardly of the propeller hub 54 and the outer diameter of the trailing edge 21 of the gear case 16 is substantially larger than the outer diameter of the propeller hub 54 to provide a sharp step down therebetween and the outer surface of the gear case 16 expands radially outwardly from the nose 18 to the trailing edge 21. In one embodiment, the nose 70 extends forwardly beyond the leading edge 17 of the drive shaft housing 14. <IMAGE>
