PROBLEM TO BE SOLVED: To provide a propulsion drive mechanism of a ship main engine which actively utilizes the surplus exhaust heat energy discharged from a supercharger and the surplus power of the supercharger for not only the assistance of power generation by a generator but also the assistance of a propeller shaft.SOLUTION: A propulsion drive mechanism of a ship main engine comprises: a propeller hydraulic motor 7 which is rotationally driven by hydraulic pressure generated by a main hydraulic pump 3; a turbine hydraulic pump 21 which is rotationally driven by a steam turbine 15; a supercharger hydraulic pump 28 which is connected to the supercharger 10, and generates hydraulic pressure; and a generator hydraulic motor 26 which is connected to the generator 25, and generates power by rotationally driving the generator. The turbine hydraulic pump and the super charger hydraulic pump are connected to the propeller hydraulic motor, and rotationally drive a propeller 5 by hydraulic pressure in conjunction with the main hydraulic pump, and the generator hydraulic motor is rotationally driven by hydraulic pressure which is generated by the main hydraulic pump, the turbine hydraulic pump, and the supercharger hydraulic pump, rotationally drives the generator, and generates power.
