Abstract

An outboard motor includes an engine including a crankshaft that is rotatable about a rotation axis extending in an up-down direction, and a crank chamber that houses the crankshaft. The outboard motor includes an oil pan disposed under the engine to retain lubricating oil to be supplied to at least the crank chamber. The outboard motor includes an oil recovery passage and a first blowby gas passage separate from the oil recovery passage. The oil recovery passage extends downward from the crank chamber to the oil pan and is configured to lead lubricating oil inside the crank chamber to the inside of the oil pan. The first blowby gas passage extends downward from the crank chamber to the oil pan and is configured to lead a blowby gas inside the crank chamber to the inside of the oil pan.
