A ship propulsion machine includes a power unit and a drive shaft that includes a power transmission device configured to selectively transmit at least one of a first power output from a first motor shaft of a first motor and a second power output from a second motor shaft of a second motor to the drive shaft. The first motor and the second motor are arranged in an upper part of the ship propulsion machine. The first motor shaft, the second motor shaft, and the drive shaft extend vertically. The second motor is arranged above the first motor. An upper portion of the drive shaft passes through the first motor shaft to be rotatable independently of the first motor shaft and reaches a region between the first motor and the second motor. The power transmission device is arranged between the first motor and the second motor.
