The invention relates to the field of ship manufacturing industry, and aims to be used for high-speed planing ships, drainage ships, yachts, motorboats and underwater vehicles. The invention makes itpossible to produce a water jet propeller integrating a motor and an impeller. Moreover, the efficiency of the propeller is fully improved, shaft power loss is eliminated, and manufacturing is more convenient due to the small number of structural components. The water-jet propeller has the advantages that the driving motor and the impeller are designed into the water-jet propeller power assembly capable of being assembled into a whole, a transmission shaft system is eliminated, and the water-lubricated bearing and motor anti-corrosion technology is adopted. The electric integrated water-jet propeller comprises an impeller flow guide pipe, an impeller, a nozzle provided with rectifying blades, a drive motor, a motor support frame which is arranged on the impeller guide pipe, and a water inlet fairing. According to a model test result, the technical effect of the integrated water-jet propeller is increased by 25-50% in the aspect of propulsion efficiency characteristics.
