Abstract: A manually transportable, internal combustion engine driven personal watercraft is described. It comprises a rigid, relatively thin fiberglass or other suitable plastic hull with inflatable tubular fabric reinforced sidewalks extending along opposed side edges of the hull from the stern to the bow. Insetted into the hull is a baseplate on which an IC engine/pump module can be readily coupled and uncoupled. The baseplate includes a water inlet scoop in fluid communication with the pump's inlet and an exhaust port which becomes aligned with the exhaust outlet of the IC engine when the two are joined. The pump's high pressure water outlet is pointed in the aft direction above the waterline and the craft is propelled by the reaction force resulting from the high velocity water jet.
