An outboard motor assembly for use as external propulsion for a watercraft includes a drive assembly, a shaft assembly, and a impeller-jet assembly coupled to the shaft assembly. The impeller-jet assembly includes an inlet stator, an exit stator, a impeller, and an external housing surrounding the stators and impeller. The inlet stator contains a plurality of blades, forcing the flow of water into an optimum direction for the impeller. The exit stator also contains a plurality of blades, which are configured to direct the flow from the impeller, removing the twist and resulting in a more efficient flow of water. The exit stator is tapered to create a more efficient flow of water. The center portion of the impeller contains a hub with an exhaust vent. In the alternative, a duct can be positioned adjacent to the outlet stator such that air is directed into the flow from the outlet.
