Abstract
An outboard motor includes an engine, a housing, a catalyst, and an engine cover. The housing includes a partitioning wall that is arranged to partition an interior of the housing into a first exhaust space connected to exhaust ports of the engine, and a second exhaust space connected to the first exhaust space. The housing is arranged such that the second exhaust space is positioned at the same side as the first exhaust space with respect to a plane that includes central axes of the plurality of the cylinders. The catalyst is positioned at a height such that at least a portion of the catalyst overlaps with the first exhaust space when viewed from a horizontal direction. The catalyst is disposed in the second exhaust space so as to guide the exhaust guided from the first exhaust space to the second exhaust space.
