ABSTRACT:
A propulsion unit for vessels has rotatably interconnected upper and lower housing portions, the upper portion being arranged to extend horizontally through the hull and permit rotation of the unit in a vertical plane for access to the lower portion. The lower portion is independently rotatable through 360.degree. to provide steering and reverse functions and includes a screw propeller positioned for rotation in a horizontal plane enclosed by fluid inlet and outlet ducts, a shallow depth inlet duct being the only projection below the hull bottom line. The unit is designed to provide normal propulsion for slow and medium speed boats and jet propulsion for light, high speed planing craft.
