An outboard motor includes a seal to seal a space between a peripheral edge of an opening of a shroud inclined surface and a peripheral edge of a cowl opening of a cowl inclined surface. The seal includes a base plate fixed to the peripheral edge of the shroud to take a rectangular annular shape having a diagonal center line and a rectangular annular seal lip extending from the base plate to be elastically contact with the peripheral edge of the cowl opening. The rectangular annular seal lip includes a hollow first seal lip. The first seal lip includes a first lip portion including a first base end and a first front end, a second lip portion including a second base end and a second front end, and a hollow portion between the first lip portion and the second lip portion. The first lip portion and the second lip portion are configured to take a chevron shape in cross-section inclined in mutually opposite directions in a free state. The first lip portion includes a surface contact region that extends to the first front end from a halfway portion between the first base end and the first front end and that is elastically surface contact with the peripheral edge of the cowl opening.
