To effectively cool the entire control board provided in an outboard motor, the outboard motor includes: an electric motor (122); a motor control board (510), one end of which is positioned higher than the other end and is configured to control the electric motor; a control case (502) located between the electric motor and the motor control board and having a cooling chamber (R) formed therein; a supply flow path (430) that connects to the cooling chamber of the control case and is configured to supply refrigerant to the cooling chamber; and a discharge flow path (432) that connects to the cooling chamber of the case and is configured to discharge the refrigerant from the cooling chamber. A discharge port (514) of the discharge flow path in the cooling chamber is located at one end of the motor control board, a supply port (512) of the supply flow path in the cooling chamber is located at the other end of the motor control board, the lower end of the discharge port is higher than the lower end of the supply port, and a first wall surface (533) on the motor control board side in the cooling chamber extends along the motor control board.
