PROBLEM TO BE SOLVED: To provide an auxiliary machine drive system in which auxiliary machines or the like can be driven at optimal power in accordance with a load of a main engine, devices are very inexpensive and simple, and electric power is hardly consumed.SOLUTION: The auxiliary machine drive system of a marine main engine comprises: a marine main engine 1 for driving a propulsion machine of a ship; a main hydraulic pump 3 for generating hydraulic pressure by power of the marine main engine; and a hydraulic mechanism 4 for supplying the hydraulic pressure supplied from the main hydraulic pump to auxiliary machines. As the auxiliary machines, the auxiliary machine drive system of the marine main engine also comprises: a fresh water pump 10 for supplying fresh water for cooling to the main engine; a sea water pump 15 for supplying sea water for cooling; and a lubricating oil pump 20 for supplying a lubricating oil discharged from the main engine to the main hydraulic pump. The fresh water pump, the sea water pump, and the lubricating oil pump are rotationally driven by auxiliary machine hydraulic motors 11, 16, 22.
