A marine drive for propelling a boat comprising:

• a housing having upper and lower spaced generally horizontal bores and an intersecting generally vertical bore extending therebetween;
• an upper input shaft in said upper horizontal bore;
• a downwardly extending driveshaft in said vertical bore and driven by said input shaft;
• a pair of lower concentric counter-rotating propeller shafts in said lower horizontal bore and driven by said driveshaft;
• a pair of counter-rotating surface operating propellers each mounted to a respective one of said propeller shafts;
• said housing comprising a lower generally horizontal torpedo portion around said lower horizontal bore, and a skeg extending downwardly from said torpedo portion, said skeg having a forward leading edge with upper and lower ends, and an aft trailing edge with upper and lower ends, wherein the upper end of said leading edge is spaced forwardly of the lower end of said trailing edge by a horizontal fore to aft distance greater than the horizontal fore to aft length of said torpedo portion, said torpedo portion having a leading edge extending from an upper end downwardly and rearwardly to a lower end, said upper end of said leading edge of said skeg meeting said lower end of said leading edge of said torpedo portion, said leading edge of said skeg extending downwardly and rearwardly from said lower end of said leading edge of said torpedo portion, the horizontal fore to aft distance between said upper end of said leading edge of said torpedo portion and said upper end of said leading edge of said skeg being less than the horizontal fore to aft distance between the aft end of said torpedo portion and said lower end of said trailing edge of said skeg.
