CA 2332069
An outboard motor includes a first case and a second case disposed below the first case. The first case houses therein an oil pan and an upper part of a drive shaft. Within the oil pan, engine oil is held. The second case has its upper edge portion coupled to a lower edge portion of the first case. The second case has a vertical wall disposed therewithin. The vertical wall separates a space within the second case into a cavity and part of an exhaust passage through which exhaust gas passes. The cavity is formed below the oil pan. This arrangement prevents the oil pan from being affected by heat of the exhaust gas. Thus, it becomes possible to prevent the engine oil held within the oil from increasing in temperature.
