To suppress air from being trapped in a water tube or a coolant flow path, an outboard motor includes a drive source including an electric motor, coolant tube through which a coolant for cooling the drive source flows, a water tube through which water from outside flows, and a heat exchanger having 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 formed therein. At least one of the coolant flow path and the water flow path includes a first flow path portion extending in a direction intersecting an upper-lower direction; a second flow path portion located at a position lower than the first flow path portion and extending in a direction intersecting the upper-lower direction; and a first folded portion connecting one end of the first flow path portion and one end of the second flow path portion. The first flow path portion is provided with a first connecting hole that is connected to the outside of the heat exchanger, and a ceiling surface forming the first flow path portion is inclined upward at an angle toward the first connecting hole.
