1. A ship propulsion machine comprising:
a ship propulsion machine main body; and
a propulsion module configured to generate a propulsion force of a ship using power generated by the ship propulsion machine main body, wherein
the ship propulsion machine main body includes:
a power source;
a tank that stores cooling liquid that cools the power source;
a heat sink that cools the cooling liquid;
a cooling liquid passage connecting the power source and the heat sink such that the cooling liquid circulates between the power source and the heat sink;
a pump configured to cause the cooling liquid to flow in the cooling liquid passage;
a mount supporting the power source, the tank, and the pump; and
a first housing part disposed below the mount and housing the heat sink,
the propulsion module includes:
a drive shaft extending in an upper-lower direction and configured to be rotated by power of the power source; and
a propulsion device connected to a lower end side of the drive shaft and configured to convert rotation of the drive shaft into the propulsion force of the ship,
the first housing part is provided with a shaft insertion portion into which the drive shaft is removably inserted,
a connection mechanism that separably connects an output shaft of the power source and the drive shaft is provided on the power source and on an upper end side of the drive shaft, and
the first housing part and the propulsion device are provided with an attachment mechanism that detachably attaches the propulsion module to a lower portion of the first housing part.
