The invention discloses a steering engine hydraulic control system and belongs to the field of ship mechanical equipment. The hydraulic control system comprises a first control module, a second control module, a third control module, a fourth control module, a first logic module and a second logic module. The first control module comprises a pump station and a stop valve. The pump station comprises a two-way hydraulic pump, a first one-way valve, a second one-way valve and an oil tank. The first control module, the third control module and the fourth control module are all the same as the first control module in structure. The second logic module and the first logic module are the same in structure. The number of working pump stations can be decreased when the temperature is excessively high, so that the heating capacity is decreased. When a ship travels normally, two pump stations are selected for working; three or four pump stations can be controlled to work when rudder turning is accelerated; and when power generation equipment is used for supplying electric power, only one pump station can be controlled to work, the power of the steering engine hydraulic control system is only half the power required during normal rudder turning, and emergency power generating equipment with the smaller power can be arranged.
