摘要： An outboard motor includes an electric motor, a drive shaft, a propeller, a propeller shaft, a cooling water flow path, a water pump including an impeller and a pump shaft, a first gear mechanism, and a second gear mechanism. The first gear mechanism includes a first gear to rotate together with the drive shaft and a second gear to mesh with the first gear and rotate together with the propeller shaft. The second gear mechanism includes a third gear, different from the first gear, to rotate together with the drive shaft, and a fourth gear to mesh with the third gear and rotate together with the pump shaft.

摘要： An outboard motor includes a drive source, a propeller, a propeller shaft extending in a first direction and rotatable together with the propeller, and a transmission shifter to transmit a drive power of the drive source to the propeller shaft. The transmission shifter includes a first assembly including an input shaft rotatable by the drive power of the drive source, a second assembly positioned around a second virtual axis, a gear transmission to transmit power between the first assembly and the second assembly and including a first gear rotatable around the first virtual axis and a second gear to mesh with the first gear and rotatable around the second virtual axis, a winding transmission to transmit power between the first assembly and the second assembly, and a switch to turn on and off the transmission of power between the gear transmission and the winding transmission.

摘要： An outboard motor includes a driving gear that is driven and rotated, and a propeller shaft that extends in a front-rear direction below the driving gear. The outboard motor includes a first transmission gear that is engaged with the driving gear and surrounding the propeller shaft, a propeller-shaft bearing that rotatably supports the propeller shaft, a first-transmission-gear bearing that rotatably supports the first transmission gear, and a support including an intervening portion between the first transmission gear and the propeller shaft. The support supports the propeller-shaft bearing between the intervening portion and the propeller shaft, and supports the first-transmission-gear bearing at a more outward position than the intervening portion in a radial direction of the propeller shaft.

摘要： A marine propulsion device includes a motive force transmission system, a propeller shaft, a housing section, and a clutch. The motive force transmission system includes a crank shaft and a drive shaft which transmits a motive force from the crank shaft. The propeller shaft transmits the motive force from the drive shaft. The housing section houses the motive force transmission system. The clutch is attached between the motive force transmission system and the housing section. The clutch permits relative rotation between the motive force transmission system and the housing section by opening a connection between the motive force transmission system and the housing section during normal rotation of the motive force transmission system. The clutch prevents relative rotation between the motive force transmission system and the housing section by connecting the motive force transmission system and the housing section during a reverse rotation of the motive force transmission system.

摘要： An outboard motor includes a cooling water flow path including an intake port to take in cooling water from outside the outboard motor and through which cooling water flows, and a water pump including an impeller and a pump shaft to rotate together with the impeller to pump the cooling water into the cooling water flow path. An inlet channel of the cooling water flow path from the intake port to the water pump is located in front of the water pump and extends along a rotation axis of the pump shaft, and an inlet that allows the passage of the cooling water and prevents entry of foreign objects is located inside the inlet channel.

摘要： An outboard motor includes a lower portion including a propeller shaft, an upper portion including a drive source to provide a rotational force to rotate the propeller shaft, and a support portion to rotatably support the lower portion relative to the upper portion about a steering shaft and rotate integrally with the lower portion. The upper portion includes a water pump assembly to suck up water from the lower portion through the support portion and supply the water to the drive source. When viewed along a shaft line direction of the steering shaft, the water pump assembly overlaps the lower portion at a first rotation position of the lower portion with respect to the upper portion, and at least a portion of the water pump assembly does not overlap the lower portion at a second rotation position of the lower portion with respect to the upper portion.
