Pressurized-water marine propeller

The utility model relates to a pressurized-water-type marine propeller, comprising a water cavity [1], a pressurized water plate [2] in the water cavity, a front pushing rod [3] and a rear pushing rod [4] driven by a driving device. The utility model has the advantages of greatly reducing the turbulence caused by the rapid rotation of the propeller, saving energy, reducing operation cost, decreasing the pollution to the environment because of the less fuel consumption, avoiding the twisting of foreign objects to the propeller from influencing the marching of the marines, protecting the wildlife in the water and having a far lower design and manufacture cost than the screw propeller.
