An outboard motor includes a first driven gear and a second driven gear, a first conical roller bearing and a second conical roller bearing, and a nut. The first driven gear and the second driven gear mesh with a driving gear. The driving gear rotates through transmission of a rotative power from an engine unit. The first conical roller bearing and the second conical roller bearing are disposed on an outer periphery of a tubular portion of the second driven gear. The first conical roller bearing and the second conical roller bearing are arranged in a front-rear direction in directions opposite from one another. The nut is disposed on the outer periphery of the tubular portion of the second driven gear. The nut is displaceable in an axial direction of the tubular portion. With the nut, a preload is applied to the first conical roller bearing and the second conical roller bearing to hold the first conical roller bearing and the second conical roller bearing to the outer periphery of the tubular portion of the second driven gear.
