The invention discloses a marine hybrid power propulsion system, which comprises a gas turbine, a gas-liquid heat exchanger and a ship body, a power system and an electric control system are arranged in the ship body, and the power system comprises a turbine and a propeller coaxially connected with the turbine; the exhaust end of the gas turbine is connected with the gas inlet end of the gas-liquid heat exchanger, and a steam outlet of the gas-liquid heat exchanger is connected with the turbine of the ship body; and the current output end of the gas turbine is connected with the current input end of the electric control system of the ship body. Heat energy and electric energy of the gas turbine are used as hybrid power, on one hand, the gas turbine converts chemical energy of fuel into electric energy which can be used for controlling the posture of the ship body and conducting vector propulsion on the ship; on the other hand, waste heat of tail gas is recycled through the gas-heat heat exchanger, and steam sprayed out of the gas-heat heat exchanger is used for directly pushing the turbine of the ship body to do work, driving propellers to rotate and pushing the ship body to advance; and vector propulsion and thermal propulsion items are combined, and the combined action efficiency can reach 80%-90%.
