摘要： An outboard motor includes a first case accommodating an engine and an upper housing below the first case. At least a portion of an exhaust passage is in the upper housing and extends downward from the engine. A second case is below the upper housing. The second case includes a torpedo portion, an exhaust inlet, an exhaust outlet, and an exhaust chamber. The torpedo portion includes an internal space and a rear end. A propeller shaft is in the internal space of the torpedo portion. The rear end of the torpedo portion is forward of at least a portion of the exhaust passage as seen in a side view. The exhaust passage is connected to the exhaust inlet. The exhaust outlet communicates with the internal space of the torpedo section. The exhaust chamber communicates the exhaust inlet with the exhaust outlet.

摘要： An outboard motor includes a first exhaust passage connected to an exhaust port and extending downward from the exhaust port through a support frame on a lateral side of a cylinder head. A first case accommodates an engine. A second case accommodates a propeller shaft. A third case is between the first case and the second case in a vertical direction. An exhaust pipe is between the first case and the second case in the vertical direction. The exhaust pipe is connected to the first exhaust passage. At least a portion of the exhaust pipe is outside the third case as seen in a side view of the outboard motor. An exterior cover is between the first case and the second case in the vertical direction. The exterior cover covers the exhaust pipe.

摘要： A marine vessel propulsion device having a metal component in contact with water. The marine vessel propulsion device includes an anticorrosive anode made of a metal material that is less corrosion-resistant than the metal component, is electrically connected to the metal component, and is disposed in contact with the water contacting the metal component, a primary reference electrode isolated from the metal component and the anticorrosive anode, and disposed in contact with the water contacting the metal component, and a potentiometer that detects a potential difference of the metal component or the anticorrosive anode with respect to the primary reference electrode.

摘要： An outboard motor includes an engine including a crankshaft that is rotatable about a rotation axis extending in an up-down direction, and a crank chamber that houses the crankshaft. The outboard motor includes an oil pan disposed under the engine to retain lubricating oil to be supplied to at least the crank chamber. The outboard motor includes an oil recovery passage and a first blowby gas passage separate from the oil recovery passage. The oil recovery passage extends downward from the crank chamber to the oil pan and is configured to lead lubricating oil inside the crank chamber to the inside of the oil pan. The first blowby gas passage extends downward from the crank chamber to the oil pan and is configured to lead a blowby gas inside the crank chamber to the inside of the oil pan.

摘要： An outboard motor includes a shift actuator, a wire connector to allow a wire of a mechanical remote control to be connected thereto and operable to be moved by the wire, a shift detector to detect that the wire connector has moved to a neutral position corresponding to a shift state of a neutral state or a drive position corresponding to the shift state of a drive state, and a controller configured or programmed to perform a control to drive the shift actuator to switch the shift state to the neutral state or the drive state based on a detection result of the shift detector.
