Abstract

In a marine drive 10 having two counter-rotating surface operating propellers 12 and 14, a drive housing 20 having upper and lower horizontal bores 22 and 24 and an has a lower horizontal torpedo portion 188 around the lower intersecting vertical bore 26 therebetween, the housing 20 horizontal bore 24. The housing 20 has a skeg 194 extending downwardly below the torpedo 188, and a water intake 192 is provided in the skeg 194. The water line is above the water intake 192, and the bottom of the torpedo 188 is at or above the plane 230 of the bottom 190 of the boat 18. In a given trimmed-in condition (Fig. 5) the torpedo 188 extends at an upward angle from the aft end thereof, and the bottom of the propeller hubs 232, 234 define a horizontal line at or above the noted plane 230. <IMAGE>
