The invention discloses a marine propeller. The marine propeller comprises a wheel hub, wherein a plurality of propeller blades are fixedly mounted at the side periphery of the wheel hub; the surface of each propeller blade is a curved surface; an arc-shaped grid plate is fixedly connected between every two adjacent propeller blades; the arc-shaped grid plates encircle the axis of the wheel hub, so that an annular pressurization system is formed; the surface radian formed by the pressurization system is matched with the curved-surface curvature formed by the surfaces of the propeller blades. By adopting the marine propeller disclosed by the invention, the pressure generated by the propeller can be increased, so that the power of the propeller is increased; the marine propeller is simple in structure, convenient to manufacture, and low in production cost.
