The present disclosure relates to an impeller driving device for a cooling pump of an electric outboard device, configured so that a gearbox housing (20) is installed on an outboard-device body (10) and an impeller housing (30) is installed against an outer surface of a right side of the gearbox housing (20) on the outboard-device body (10) to drive the impeller for the cooling pump of the electric outboard device.A propeller shaft (1) provided in a propeller driving motor passes vertically through a central portion of the gearbox housing (20) and the outboard-device body (10).In the gearbox housing (20), a first bevel gear (2) having on a center thereof a first one-way bearing (3) that is locked clockwise and unlocked counterclockwise is coupled to an upper portion of the propeller shaft (1), a second bevel gear (5) having on a center thereof a second one-way bearing (4) that is locked counterclockwise and unlocked clockwise is coupled to a lower portion of the propeller shaft (1), and a third bevel gear (6) having on a center thereof the impeller shaft (7) that is coupled to extend to the right and penetrates the gearbox housing (20) and an inside of the impeller housing (30) is positioned between a right side of the first bevel gear (2) and a right side of the second bevel gear (5) to transmit rotating force of the first and second bevel gears (2, 5) as counterclockwise rotating force.In the impeller housing (30), an impeller blade (8) is installed on a right side of the impeller shaft (7), so that, as the propeller shaft (1) rotates clockwise or counterclockwise, the impeller blade rotates counterclockwise, thus sucking water through an inlet (32) that is provided in a lower portion of the impeller housing (30) and discharging water through an outlet (34) that is provided in an upper portion of the impeller housing (30), whereby direct water cooling of the propeller driving motor is performed.
