JET PUMP FITTING STRUCTURE FOR SMALL SURFACE CRUISING BOAT

PROBLEM TO BE SOLVED: To prevent the vibrations of a jet pump from being transmitted to a hull via fitting bolts by fitting the jet pump to the recess of a hull bottom face from the rear, and inserting vibration absorbing members between the bolts and fitting holes. SOLUTION: A duct inlet component member 16 arranged while the front section of a circular portion 16a is coupled with the coupling section 13b of a recess 13 is screwed to the step section 13c of the recess 13 by bolts 41 through the bolt screwing holes 16d of a fitting insertion section 16c. A jet pump 17 is screwed to the bolt screwing holes 16d of the fitting insertion section 16c by bolts 45 inserted from the rear into the fitting holes 31b penetrated in the hull longitudinal direction in the fitting sections 31a provided at the rear end outer periphery section of a housing front member 31 via vibration absorbing members 44 constituted of a metal collar member 43 and a rubber elastic material.
