Abstract
A sealing structure of an outboard motor includes a bottom cowling covering a lower part of an engine, a top cowling covering an upper part of the engine, and a sealing material via which the top cowling is coupled to the bottom cowling. The sealing material includes an installation base member fitted on the bottom cowling. The installation base member has a roughly U-shaped cross-section with an opening into which the top end of the bottom cowling is inserted. A hollow seal member is provided on an outer wall of the installation base member and makes elastic contact with an inner surface of the bottom end of the top cowling. A lip projects outward from the hollow seal member. An upper surface of the lip makes elastic contact with a bottom surface of the bottom end of the top cowling.
