摘要： An outboard motor includes a bracket, an engine, an upper case, a lower case, a cavitation plate, a transmission, a cooling water passage, a first pump, and a second pump. The transmission includes a drive shaft and a propeller shaft. The cooling water passage is connected to the engine and located in the upper case and the lower case. The first pump is below a lower end of the bracket. The first pump is connected to the transmission and operable to send cooling water to the engine through the cooling water passage. The first pump is a non-positive displacement pump. The second pump is driven by a driving force from the transmission and operable to send the cooling water to the engine through the cooling water passage.

摘要： A marine propulsion device includes a first gear, a second gear, a third gear, a case, a partition wall, and a first flow path. The case includes an internal space in which the first gear, the second gear, and the third gear are located. The partition wall is located between the second gear and the third gear in the internal space. The partition wall partitions the internal space into a first space and a second space. The second gear is located in the first space. The third gear is located in the second space. The first flow path communicates the first space with the second space. The first flow path is located on a same side as the first gear with respect to a center line of the second gear and the third gear.

摘要： An outboard motor includes a bracket, an upper case, a lower case, a drive shaft, a propeller shaft, a cooling water passage, a water pump, and an electric motor. The outboard motor is attached to a watercraft via the bracket. The upper case is below the engine. The lower case is below the upper case. The drive shaft is in the upper case and the lower case. The propeller shaft is connected to the drive shaft. The propeller shaft is in the lower case. The cooling water passage is connected to the engine. The cooling water passage is in the upper case and the lower case. The water pump is below a lower end of the bracket to deliver cooling water to the engine through the cooling water passage. The electric motor is operable to drive the water pump.

摘要： An outboard motor includes a drive shaft, a coupling to connect a first shaft and a second shaft of the drive shaft together, and a transmission including a dog clutch to transmit a rotation of the drive shaft to a propeller shaft. The coupling includes a first portion attached to the first shaft, a second portion attached to the second shaft, and a damper. The first portion includes first claws arranged along a rotation direction of the drive shaft. The second portion includes second claws between adjacent ones of the first claws in the rotation direction. The damper includes an elastic portion interposed between adjacent ones of the first claws and the second claws in the rotation direction.

摘要： A marine propulsion device includes a drive shaft, a propeller shaft, and a lower case that houses the propeller shaft. In the marine propulsion device, a power generator generates power using a torque of the drive shaft or the propeller shaft, and the generated power is supplied to an electric actuator to drive a driven unit through a first power line, wherein the electric actuator is controlled by a controller. At least a portion of the driven unit, at least a portion of the electric actuator, at least a portion of the power generator, and the first power line are located in the lower case.

摘要： An outboard motor includes an engine, a fuel tank, a fuel pathway, a fuel pump, and a controller. The engine includes a fuel injector. The fuel tank includes an internal space in which fuel is stored. The fuel pathway is connected to the fuel injector and the fuel tank. The fuel pump is disposed in the fuel pathway, and supplies the fuel from the fuel tank to the fuel injector. The controller controls the fuel pump. The controller determines whether or not a start condition, indicating that air has entered the fuel pathway, is satisfied. The controller is configured or programmed to execute an air releasing control to open the fuel injector and drive the fuel pump when the start condition is satisfied.

摘要： A marine propulsion device includes a first gear, a second gear, a third gear, a circulator, a case, and an attachment body. The second gear is meshed with the first gear. The third gear is meshed with the first gear, and the third gear is coaxial with the second gear and opposed to the second gear. The circulator is between the second gear and the third gear. The case includes an internal space in which the first gear, the second gear, the third gear, and the circulator are located. The case includes an attachment hole to which the circulator is attached. The attachment body is inserted into the attachment hole so as to attach the circulator to the case.

摘要： A multi-cylinder engine includes a plurality of cylinders that are fired at uneven intervals. A controller is configured or programmed to overlap a time period that a plunger increases a pressure in a pressurizing chamber and a time period that an electromagnetic valve remains opened in at least the longest one of the intervals at which the firing is conducted in the plurality of cylinders.
