An outboard motor includes a steering mechanism including a pinion located in a central portion of an outboard motor body in a right-left direction and operable to rotate together with the outboard motor body, and a rack operable to linearly move to rotate the pinion, and extending along a forward-rearward direction of the outboard motor body.

An outboard motor includes an engine, a fan, and a top cowl assembly. The fan suctions air around the engine and discharges the air through a discharge port. The top cowl assembly includes a top cowl to house the engine and the fan, and a cover to cover at least a portion of an outside of the top cowl. The top cowl assembly includes an exhaust port to communicate with the discharge port via an exhaust channel. At least a portion of the exhaust channel is defined by a surface of the top cowl and a surface of the cover.
