Abstract
An outboard motor includes a mount on which an engine is mounted, an engine cover, and a sealing structure. The engine cover is divisible into a top portion, a front bottom portion, and a side bottom portion. A first seal in the sealing structure integrally includes a first portion, a second portion, and a third portion. The first portion seals the boundary between the top portion, the front bottom portion, and the side bottom portion. The second portion seals the boundary between the front bottom portion, the mount, and the side bottom portion. The third portion seals the boundary between the front bottom portion and the side bottom portion.
