In a ship propulsion machine, a power unit includes a connecting member and a switching mechanism which are arranged between a first motor and a second motor arranged above the first motor. The power unit includes a lower end portion configured to be connected to an upper end portion of a first motor shaft; and an upper end portion configured to be connected to a lower end portion of the second motor shaft. The switching mechanism is configured to switch a connection mode by moving the connecting member upward or downward, so as to be selectable from at least two modes of a mode (a) in which both the first motor shaft and the second motor shaft are connected to the drive shaft, a mode (b) in which the first motor shaft is connected, and a mode (c) in which the second motor shaft is connected.
