In an outboard motor, a feed passage, through which a lubricating oil that flows upward from a gear mechanism due to rotation of the gear mechanism, extends upward from a gear chamber and includes a first feed passage that extends from the gear chamber to a connection passage via a first upstream passage, a spiral passage, and an interior of an upper bearing, in that order. The feed passage further includes a second feed passage that extends from the gear chamber to the return passage while bypassing the spiral passage via a bypass passage. The bypass passage includes two ends spaced apart in a circumferential direction of the driveshaft and is disposed around the spiral passage.
