Disclosed is a marine propeller with detachable blades (1), the marine propeller comprising a propeller hub (2) and the blades (1). Cambered mounting plates (3) are connected to the bottom ends of the blades (1). A plurality of mounting holes (5) are provided on the mounting plate (3). A plurality of slotted holes (6) arranged opposite the mounting holes (5) are provided in the propeller hub (2). A bolt (4) is inserted into the mounting hole (5) and the slotted hole (6) and connected therein. When the marine propeller with the detachable paddles (1) is maintained and repaired, it is not necessary to dismount and repair the whole propeller, only to dismount the paddle (1) needed to be maintained and repaired, so that the dismount operation saves both time and labour, and since it is not necessary to replace the whole propeller, the invested cost is low.
