ABSTRACT:
A marine propulsion system, incorporating a jet pump, provides improved mass flow through the pump by utilizing an inlet opening which initially diverges to a transition point in front of an impeller and then diverges from the transition point past the impeller region to the outlet opening of the pump. Significantly increased flow rates per horsepower are achieved by reducing the normal restrictions caused by the inlet and outlet openings of known pumps. A transmission is provided to connect the output shaft of an engine to the drive shaft of the impeller. Either a V-drive or a torpedo-type gear housing can be employed.
