ABSTRACT:
A boat is provided with an integral jet power unit encased in a waterproof housing. The hull has a well or compartment open at top and bottom which removably receives the power unit. Retaining elements hold the power unit in place in the compartment. Resilient gasket seals the housing in the well, reduces transmission of vibration and cushions the thrust generated by the jet. The walls of the well are sealed to the bottom of the boat hull so that the hull will not leak when the power unit is removed. The invention may be embodied in various hull constructions including folding and inflatable boats, where handling the hull and power unit separately greatly enhances operation, transport and storage.
