  "textContent": "An outboard motor (1) includes a first casing (3) and a second casing (4) disposed below the first casing. The first casing houses therein an oil pan (8) and an upper part of a drive shaft (10). Within the oil pan, engine oil is held. The second casing has its upper edge portion (4a) coupled to a lower edge portion (3a) of the first casing. The second casing has a vertical wall (23) disposed therewithin. The vertical wall separates a space within the second casing into a cavity (25) and part (24) 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 pan from increasing in temperature.",
