To improve the cooling efficiency of the various devices that constitutes the outboard motor, an outboard motor includes a drive source, a motor control device, one or multiple coolant tubes, a pump, and an air vent. The drive source includes an electric motor. The motor control device is arranged at a position higher than the electric motor and controls the electric motor. The coolant tube includes at least a part of the coolant flow path through which the coolant that cools the electric motor and the motor control device circulates. The pump is connected to the coolant tube to pump the coolant. The air vent is located at an uppermost portion of the coolant flow path. The coolant flow path is configured such that the coolant pumped by the pump flows in the order of the motor control device, the air vent, and the electric motor.
