An outboard motor includes an oil passage that through which an oil flows from the shift chamber to a gear chamber. A circular recessed portion is formed on an upper surface of the gear chamber. A rectangular recessed portion communicating with the circular recessed portion is formed on a portion of the upper surface adjacent to the circular recessed portion. The rectangular recessed portion includes a front surface facing a side surface of the circular recessed portion, a left surface located on a reverse side of a rotation direction of the drive gear with respect to the front surface, and a right surface located on a side of the rotation direction with respect to the front surface. An outlet of the oil passage is arranged on the front surface at a position closer to the left surface than to the right surface.
