The invention relates to a propeller for a ship, especially to a full-revolution series duct type marine propeller mainly comprising a stator component, a driving transmission component, and a driven transmission component. During the propelling operation, a ship propulsion drive unit drives a driving shaft to rotate along the rotation direction of the driving shaft; on the basis of engagement of a bevel gear I and a bevel gear II, a driven shaft drives a propeller component to rotate along the rotation direction of the propeller; and a water flow is influenced by conveying of a two-stage liquid pump unit and is injected from an outer side end of the propeller component to push the ship to sail forward. When the ship turns for running, a ship turning drive unit drives a revolving shaft to rotate along the rotation direction of the revolving shaft, the revolving shaft drives the propeller component by the stator component to make omnidirectional horizontal revolution, and the sailing direction of the ship is changed by changing the water flow injection direction. According to the propeller, tips of blades are connected with the inner surface of the duct, thereby guaranteeing the high structural strength and rigidity. A plastic or composite material can be used for manufacturing the propeller.
