PURPOSE:To enable a mounting flange for a propulsion machine to be properly mounted onto a partitioning wall between an engine room and a recessed section for the propeller. CONSTITUTION:An engine room 20 and a recessed section 40 for a propulsion machine are formed while being adjacent to each other back and forth in the ship's bottom section of a small ship, a partitioning wall 41 partitioning both of them, the bottom wall 42 of the recessed section 40, which is perpendicularly intersected with the aforesaid wall, and both of side walls 44 are integrally formed into one by a molding die, a molded part is formed in such a way that the side of the recessed section 40 for the propulsion machine is turned out to be a molding surface, and the flange surface of a mounting flange 31 for a jet propeller 3 is brought into contact with the partitioning wall 41 so as to be installed. |
