Abstract
An outboard motor includes an engine, an engine cover accommodating the engine, and an intake path between the engine cover and the engine. The intake path directs external air to the engine. The engine cover includes an upper cover and a lower cover. The upper cover includes an opening to take external air into the intake path. The intake path includes a first airflow passage, a second airflow passage, and an airflow space. The first airflow passage is at least partially defined by an inner surface of the engine cover, and downwardly directs the external air. The second airflow passage is at least partially defined by the inner surface of the engine cover, and upwardly directs the external air. The airflow space is above the lower cover and continues to the first airflow passage and the second airflow passage.
