ABSTRACT OF THE DISCLOSURE The marine propulsion device includes a lower unit which has a gear case normally submerged in water and which is arranged to discharge engine exhaust gases through the propeller hub. The leading end of the gear case has a tapered nose and a trailing end of the gear case has a generally circular cross section and terminates in a generally vertical trailing edge located forwardly of the propeller hub. The outer diameter of the trailing end of the gear case is substantially larger than the outer diameter of the propeller hub to provide a sharp step down therebetween and the outer surface of the gear case expands radially outwardly from the nose to the trailing edge. In one embodiment, the nose extends forwardly beyond the leading edge of the drive shaft housing.
