Impeller design and efficiency is strongly linked to the other components that make up the jet-pump, i.e., gullet volumetric area, laminar transition of the intake housing, stator blade area and angle of trajectory, venturi rate of compression, venturi "bowl" area, exiting orifice dimension, mass and weight of the hull, and pump placement or. Jet boats need a stream of presurized water to move. iirc archimedes screws need to move slow and are only used for lifting fluids without adding pressure. for what its worth i am an engineer and use to work for an industrial pump manufacture. never did any impeller design tho..
