The invention belongs to the technical field of propellers, and particularly relates to a water-air dual-purpose propeller with double motors arranged in parallel. Comprising a rack, a propeller, an underwater motor, an aerial motor and a clutch transmission device, the underwater motor and the aerial motor are arranged on the rack in parallel, the propeller is arranged on an output shaft of the aerial motor, and the propeller is connected with the output shaft of the underwater motor through the clutch transmission device; and switching between an underwater motor driving mode and an air motor driving mode is realized through the clutch transmission device. The double motors are adopted, high-rotation-speed and low-torque operation of the propeller in the air and underwater low-rotation-speed and high-torque operation of the propeller are achieved through the gears which are large in reduction ratio and capable of being separated and combined, the design difficulty of the motors is greatly reduced, the operation efficiency of the motors is improved, efficient propelling underwater and in the air is achieved, and the propeller has the advantages of being compact in structure, light in weight, high in propelling efficiency and the like.
