PROBLEM TO BE SOLVED: To provide an outboard engine which achieves weight reduction of a cylinder body and inhibits troubles caused by a blow-by gas interrupting flow of a lubrication oil recovered into an oil pan.SOLUTION: An outboard engine 4 includes: an oil pan 61 which is disposed below an engine 9 and stores a lubrication oil supplied to at least a crank chamber 44. The outboard engine 4 includes: an oil recovery passage (a first oil recovery passage 73) which guides the lubrication oil in the crank chamber 44 into the oil pan 61; and a first blow-by gas passage 62 which is different from the oil recovery passage. The oil recovery passage 73 and the first blow-by gas passage 62 extend downward from the crank chamber 44 to the oil pan 61. The first blow-by gas passage 62 guides the blow-by gas in the crank chamber 44 into the oil pan 61. |
