The invention relates to the technical field of outboard engines, and discloses a circulating water-cooled electric energy outboard engine which comprises a motor, a controller and a water pump, a cooling flow channel is formed in the motor, and the water pump, the cooling flow channel and a controller cooler are connected through a pipeline to form a closed loop; the pipeline comprises a connecting pipe I for connecting the water outlet of the water pump with the water inlet of the controller cooler, a connecting pipe II for connecting the water outlet of the controller cooler with the water inlet of the cooling flow channel, and a connecting pipe III for connecting the water outlet of the cooling flow channel with seawater; according to the closed loop, seawater flows into the controller cooler through the first connecting pipe, then flows into the cooling channel through the second connecting pipe and finally returns to the seawater through the third connecting pipe, a water inlet pipe is installed at one end of the water pump, and a supporting platform is installed outside the water inlet pipe. According to the circulating water-cooled electric energy outdoor unit, seawater is introduced into the cooling system and circularly flows, so that the temperature of the motor and the controller is effectively reduced, and the service life is prolonged.
