The invention provides a liftable and lowerable marine auxiliary steering device, and the components are as following: a motor (2) is arranged in a boat body (1), and an output shaft (2a) is arranged on the motor (2). The liftable and lowerable marine auxiliary steering device is characterized in that a transmission shaft (4) is connected onto the output shaft (2a) through a universal joint (3); a coupler (4a) is arranged on one end of the transmission shaft (4); a hydraulic cylinder (5) is arranged, and two ends of a tubular piston rod (6) of the hydraulic cylinder (5) penetrate through a piston (5); a gear box (7) is connected to the upper end of the piston rod (6); the lower end of the piston rod (6) penetrates through the boat body (1) so as to be connected with a propeller (8). The liftable and lowerable marine auxiliary steering device is simple in structure and convenient to be operated, and the propeller can be driven to stretch up and down through the action of the hydraulic cylinder, and the boating resistance generated when the steering device does not work can be effectively reduced, and the probability that the auxiliary steering device is wound by underwater impurities is reduced.
