Jet propulsion drive for water craft - incorporates guide blade transversely located in a flow channel of nozzle inlet

摘要

The propulsion has a nozzle projecting rearward and a motor-driven centrifugal pump to eject water through it. The water flow channel extends forward from the pump inlet downwards through the hull, and has an inlet aperture on the same level as the hull bottom. The channel has an internal guide blade located across it, to divide it into an upper and a lower section. the blade extends outwards, across a line between the front and the rear inlet edge. The blade has a horizontal front edge, under teh lower channel inlet edge, and extends rearwards into the channel.
