摘要： An outboard motor includes an engine housed in a cowling and disposed above an upper case housing a driveshaft. A gear mechanism transmits a rotation of the driveshaft to a propeller shaft housed in a lower case disposed below the upper case. The gear mechanism is housed in an oil storage chamber of the lower case and is lubricated by a lubricating oil inside the oil storage chamber. An oil passage includes a lower oil port opening at the oil storage chamber, an upper oil port positioned higher than the lower case, and a longitudinal passage extending in an up/down direction inside the lower case.

摘要： 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.

摘要： A marine propulsion device includes a power source, a steering handle, and an accelerator grip that moves with respect to the steering handle. A movement region of the accelerator grip includes a forward movement rotation region, a reverse movement rotation region and an axis movement region. In the forward movement rotation region, the accelerator grip is operated to rotate so as to obtain a drive force in a forward movement direction. In the reverse movement rotation region the accelerator grip is operated to rotate so as to obtain a drive force in a reverse movement direction. The axis movement region is provided between the forward movement rotation region and the reverse movement rotation region. In the axis movement region, the accelerator grip is moved in the extensional direction of a rotation axis.
