1. An outboard motor that propels a hull by rotating a propeller with a drive source, comprising:
a first drive shaft that outputs a torque from the drive source;
a second drive shaft that is disposed parallel to the first drive shaft and transmits the torque to an output shaft to which the propeller is connected; and
a decelerator that is disposed between the first drive shaft and the second drive shaft and transmits the torque from the first drive shaft to the second drive shaft,
wherein the drive source is disposed below the decelerator,
the drive source is an electric machine disposed longitudinally,
a liquid level height of a liquid that cools the electric machine is set within a range in which a coil provided in a lower portion of a stator is immersed and is located below a rotor, and
a suction port of a liquid pump is provided on a side on which the coil is disposed and in the vicinity of the coil.
