To provide a propulsion mechanism which is a simpler structure than before and capable of stably operating in a propulsion mechanism of a DF engine driven by selecting a diffusing combustion and a premixed combustion, and of an electric propulsion ship powered by battery.SOLUTION: A propulsion mechanism 3 of an electric propulsion ship 1 comprises a generator 15 to generate electricity with a DF engine 23 driven by selecting diffusion combustion of liquid fuel or by premixed combustion of gas fuel, a battery 13, an electric motor 11 to drive a propeller 17 when power is supplied to the electric motor from the generator 15 or the battery 13, and a switching controller 9 to control the connecting selection of the generator 15, the battery 13, and the electric motor 11, and to control the distribution of power. The electric motor 11 is a DC motor. The switching controller 9 connects the electric motor 11 and the battery 13 when a load change of the electric motor 11 is beyond the predetermined threshold in the case that the motor 11 with the connected state to the generator 15 is in a power running by receiving power supply from the generator 15 while the DF engine 23 is driven by the premixed combustion.SELECTED DRAWING: Figure 1
