a drive shaft that is connected to the drive source and extends in a vertical direction;
a propeller shaft that is connected to a lower end portion of the drive shaft to intersect the drive shaft and is provided with the propeller;
an upper case that accommodates the drive source;
a lower case that accommodates the propeller shaft; and
a height adjusting unit that adjusts a height position between the upper case and the lower case in the vertical direction,
wherein the height adjusting unit includes
a first member that is disposed coaxially with an axis of the drive shaft, is rotatably supported around the axis with respect to one of the upper case and the lower case, and has a screw portion coaxial with the axis,
a second member that is fixed to the other of the upper case and the lower case and is screwed to the screw portion of the first member,
