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 pump station, a second pump station, a first stop valve, a second stop valve, a first isolating valve and a second isolating valve. The first pump station comprises a first two-way hydraulic pump, a first one-way valve, a second one-way valve and a first oil tank. The second pump station comprises a second two-way hydraulic pump, a third one-way valve, a fourth one-way valve and a second oil tank. The first stop valve, the second stop valve, the first isolating valve and the second isolating valve are all two-position four-way valves. A first oil port of the first two-way hydraulic pump communicates with an oil outlet of the first one-way valve. A second oil port of the first two-way hydraulic pump communicates with an oil outlet of the second one-way valve. Both an oil inlet of the first one-way valve and an oil inlet of the second one-way valve communicate with the first oil tank. The hydraulic control system is simple in structure, the hydraulic control system can be regulated by only operating the first stop valve, the second stop valve, the first isolating valve and the second isolating valve, and operation is convenient.
