1. An outboard motor comprising:
an engine; a drive shaft extending vertically to transmit rotational power from the engine; a driving gear provided to rotate in synchronization with a lower end of the drive shaft; and a driven gear provided in a propeller shaft rotating in synchronization with a propeller to mesh with the driving gear, wherein the drive shaft has a first input shaft that receives rotational power transmitted from the engine, and a second input shaft that is arranged coaxially with the first input shaft to receive rotational power transmitted from the first input shaft, a shift unit is provided between the first and second input shafts to switch a shift position,
the shift unit havingan upper gear provided in a lower end of the first input shaft to rotate in synchronization,a lower gear provided in an upper end of the second input shaft to rotate relatively to the second input shaft,an intermediate gear provided to rotate in synchronization with an intermediate shaft extending to the rear side perpendicularly to the drive shaft and mesh with the upper and lower gears at all times, anda clutch body that is arranged between the upper and lower gears and rotates in synchronization with the second input shaft to control connection/disconnection of rotational power from the first input shaft to the second input shaft and switch a rotation direction, while the clutch body moves along the second input shaft to engage with the upper or lower gear, or while the clutch body does not engage with any one of the upper and lower gears, and an accessory is operated by receiving the rotational power transmitted via the intermediate shaft. |
