Watercraft with twin jet propulsion units

An improved mounting arrangement for a twin jet propulsion unit eases the assembly of the system, as well as enhances the performance of the system. A unified mounting plate supports the propulsion units and offer a degree of adjustability which permits the propulsion units to be precisely aligned with desired longitudinal axes defined by the watercraft hull, as well as with each other. In addition, the rigidity provided by the mounting plates tends to hold the propulsion units, which cantilever rearward from the mounting plates, in the desired positions. As a result, additional support structure and fasteners can be removed from between the jet propulsion units and they can be spaced closer together so as to generally match a desired spacing between the inlet openings of the associated intake ducts.
