An intake manifold is connected to a cylinder of an engine, and extends backward from the cylinder. A throttle body is attached to the intake manifold. As seen in a plan view of an outboard motor, the throttle body is disposed backward of a head cover, while being disposed inward of a lateral end of the intake manifold in a right-and-left direction of the outboard motor.

Outboard motor

An outboard motor includes an engine including a crankshaft, a generator including a rotor that rotates together with the rotation of the crankshaft and a stator in which a coil is wound so as to face the rotor, and a fan including a blade disposed coaxially with the rotor, provided separately from the rotor, and that rotates together with the rotation of the rotor.

In an outboard motor, one of an engine control unit and a power supply control unit is mounted on a first side surface of an engine, and the other of the engine control unit and the power supply control unit is mounted on an upper surface of the engine.
