A motorized surfboard device can be ridden by a rider comprises a surfboard having an underside surface and a top side surface. The motorized surfboard device also includes a motive device mounted on the underside surface of the surfboard. The motive device comprises a motor and a rotatable propeller, in which the motor is connected to the rotatable propeller for rotating the same. The propeller comprises a cylindrical body with a surface configuration including at least one groove in a surface of the rotatable propeller body, wherein the at least one grove defines raised ridges between the at least one groove, the edges of the grooves being rounded, the at least one comprising a depth. The motorized surfboard device including a control apparatus having at least one of a foot-controlled switch, a hand-operated and controlled steering column, and a hand controlled switch. The control apparatus controlling at least one of on/off operation of the motor and variable speed of the motor.
