A ship propulsion machine includes a ship propulsion machine main body and a propulsion module. The ship propulsion machine main body includes a power source, a tank storing cooling liquid, a heat sink cooling the cooling liquid, a cooling liquid passage connecting the power source and the heat sink, a pump causing the cooling liquid to flow in the cooling liquid passage, a first housing part housing the heat sink. The propulsion module includes a drive shaft rotated by the power source and a propulsion device converting rotation of the drive shaft into the propulsion force. A connection mechanism separably connecting an output shaft of the power source and the drive shaft is provided on the power source and on the drive shaft. The first housing part and the propulsion device are provided with an attachment mechanism detachably attaching the propulsion module.
