The invention relates to an immersed water-jet propulsion water surface ship. The ship comprises a stern and a propulsion device, and the stern is provided with a groove; the propulsion device comprises a propulsion shaft, a rotating impeller, rectifying blades and a guide pipe, the outer wall of the guide pipe is connected into the groove, and the propulsion shaft, the rotating impeller and the rectifying blades are all located in the guide pipe; one end of the propulsion shaft penetrates through the stern to reach a cabin in the ship; the rotating impeller is connected with the propulsion shaft in a sleeving mode, and the rectifying blades are rotationally connected with the propulsion shaft. The rectifying blades are located on the downstream of the rotating impeller so that the rectifying blades can be used for rectifying water flow generated after the rotating impeller rotates to do work. The immersed water-jet propulsion water surface ship provided by the invention has the advantages in the aspects of propulsion efficiency and vibration noise comprehensive performance.
