The invention discloses a magnetic coupling underwater propeller which comprises a shell and an end cover, wherein a sealed chamber is formed at the center of the shell; a positioning column is formed at the inner bottom of the sealed chamber; a motor stator is fixedly arranged on the positioning column; a driving circuit is mounted in the sealed chamber; a capsule is formed at an opening of the sealed chamber; a motor rotor supporting hole is formed on the end cover; a motor rotor matched with the motor stator is supported on an external circle of the sealed chamber and the motor rotor supporting hole; a propeller is fixedly connected to the motor rotor; a hub diameter ratio of the propeller is 0.59-0.68; a curved surface structure is adopted for an inner side wall of a non-metallic waterproof shell; a flow guide pipe for the propeller is formed by the non-metallic waterproof shell and the end cover; flow guide covers are fixedly connected with both of the end cover and the non-metallic waterproof shell. The magnetic coupling underwater propeller has the advantages of compact structure, small volume, high efficiency and stable and reliable property.
