ABSTRACT:
A water jet propulsion module is generated about a central axis and has an inlet opening and a discharge opening concentric with said axis. The module includes a stator having an inner wall and an outer wall with curved stator vanes connected between said inner and outer walls. An impeller shroud is adjustably connected to the outer stator wall. A motor secured to the stator drives a planetary gear drive attached to an impeller by a parabolic impeller cone. The impeller draws water into the inlet opening and drives the water past the stator vanes out of the discharge opening along a substantially linear path at high speed and pressure.
