Abstract
A waterjet propulsion system having a transversely mounted engine driving one or more pumps with multiple inlets located so that at low speed, subplaning operations a greater flow of water is available, but at higher, planing speeds some inlets vent and a reduced flow is delivered to the pumps. This is accomplished by locating some inlets between the subplaning waterline and the planing waterline of the vehicle.
