An outboard motor includes a drive source including an electric motor, a coolant tube through which a coolant to cool the drive source flows, a water tube through which water from outside the outboard motor flows, and a heat exchanger including a coolant flow path through which the coolant from the coolant tube flows and a water flow path through which the water from the water tube flows. At least one of the coolant flow path and the water flow path includes a first flow path, a second flow path lower than the first flow path, and a first bent connector connecting one end of the first flow path and one end of the second flow path. The first flow path includes a first connecting hole connected to an outside of the heat exchanger, and an upper surface inclined upward at an angle toward the first connecting hole.
