Abstract
An outboard motor includes an engine, an exhaust passage member, and an idle exhaust passage member. The exhaust passage member defines a main exhaust passage through which exhaust gases of the engine are guided to a main exhaust port disposed in the water, and also defines a portion of an idle exhaust passage through which exhaust gases in the main exhaust passage are guided to an idle exhaust port opened to the atmosphere. The idle exhaust passage member includes an upstream end connected to the exhaust passage member and a downstream end that defines the idle exhaust port and is disposed at a higher position than the upstream end. The idle exhaust passage member is made of a flexible material, and is integrally formed from the upstream end to the downstream end.
