摘要： An intake device for outboard motors, which makes it possible to improve intake performance and reduce the size of the device at the same time. Cylinder banks have a plurality of cylinder bores arranged in a vertical direction, and extend rearward to form a V shape. Intake ports of the respective cylinder bores are formed in the cylinder banks to open in the inner sides of the V shape. An intake manifold is connected to the intake ports. A surge tank is connected to the intake manifold. A throttle body is connected to the surge tank. The surge tank comprises a plurality of intake passage members connected to the respective cylinder bores via the intake manifold, wall members provided between respective adjacent ones of the intake passage members, and a lid member configured to hermetically close a space defined by the intake passage members and the wall members.

摘要： A shift system for outboard motors, which is reduced in size, and is capable securing compatibility with an outboard motor of a type for which the shift operation is manually performed using a shift cable. A motor-driven shift actuator is disposed at a location forward of and to the right of an engine within an engine cover covering the engine. A clutch motor is provided for the actuator and disposed at a location rearward thereof, with a motor output shaft disposed in a manner extending forward, and is operated in response to the detected vessel operator's shift. An actuator output shaft is disposed at a location forward of the clutch motor and extends downward from a front part of the actuator. The actuator output shaft rotates in accordance with rotation of the motor output shaft. A clutch shaft is disposed below the actuator and rearward of the actuator output shaft. A first linkage is disposed on the right side of the actuator, as viewed in plan view, and connects between the actuator output shaft and the clutch shaft.
