The boosting structure comprises a duct and a propeller located in the duct, a mounting cylinder with the bottom open is arranged on the lower portion in the duct, a driving part is mounted in the mounting cylinder, and a driving shaft of the driving part extends out of the top face of the mounting cylinder and then is connected with the propeller. The propeller is composed of a propeller cap and three spiral blades evenly distributed on the peripheral side of the propeller cap, the propeller cap is in an inverted bowl shape, the blades are spirally arranged on the outer circumference of the propeller cap, a gap is reserved between the outer edge of each blade and the inner face of the duct, and the gap is smaller than 1 mm. The boosting structure of the underwater booster has the advantages of being good in rotation stability, large in boosting thrust, high in efficiency, long in service life and the like.
