Abstract
An outboard motor includes a drive source, a drive shaft, a steering shaft, a case, and an angle detection sensor. The drive shaft extends in an upper-lower direction and is rotatable by the driving force of the drive source. The hollow tubular steering shaft surrounds an outer circumference of the drive shaft. The case is located lower than the drive source, and an oil chamber is structured to store oil, and at least a portion of the steering shaft is housed in the oil chamber. The angle detection sensor is located higher than the oil chamber to detect the rotation angle of the steering shaft.
