Abstract
An outboard motor includes an upper case, a lower case including an oil reservoir chamber, an oil flow passage, and an oil flow passage shutoff valve. When the lower case is detached from the upper case, the oil flow passage is separated into an upper oil flow passage in the upper case and a lower oil flow passage in the lower case and connected to the oil reservoir chamber. The oil flow passage shutoff valve opens the lower oil flow passage in a state in which the lower case has been attached to the upper case. The oil flow passage shutoff valve closes the lower oil flow passage in a state in which the lower case has been detached from the upper case.
