摘要:
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 including an oil retaining portion, a cooling water passage disposed along an outer wall surface of the oil retaining portion, an oil recovery passage extending downward from the crank chamber to lead lubricating oil inside the crank chamber to the inside of the oil retaining portion, and a guide member. The guide member includes a shielding portion disposed inside the oil recovery passage so as to be located over an opening of the oil retaining portion, and a guide hole disposed inside the oil recovery passage so as to be located over an inner wall surface of the oil retaining portion. The guide member is configured to guide lubricating oil to the guide hole by the shielding portion and allow lubricating oil to flow down to the inner wall surface of the oil retaining portion from the guide hole.
