A water jet propulsor powered by an integral canned electric motor includes a hollow housing having a hermetically sealed stator mounted therein. The stator is electrically connected to a source of electrical energy in the vessel. An impeller assembly that includes a tubular suction shroud and impeller is rotatably mounted inside the housing. The impeller assembly includes a hermetically sealed rotor which is mounted around the suction shroud and positioned inside the stator in operative association therewith. Energizing the stator rotates the rotor, which in turn rotates the impeller to pump water from the intake end of the housing to the outlet end of the housing and adds velocity and head to the water to be discharged from the outlet end. The discharged water creates thrust which propels the vessel.
