Abstract
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.
