A double-propeller square tube ship propeller relates to a ship thruster, and comprises a left engine, a left propeller, a right engine, a right propeller and a square tube-shaped shell; the left engine and the right engine are respectively mounted on the left and right outer sides of the square tube-shaped shell; the left propeller and the right propeller are symmetrically mounted inside the square tube-shaped shell left and right; a front included angle between the rotation plane of the left propeller and the rotation plane of the right propeller is less than 160 degrees; an included angle between the rotation plane of the left propeller and a left plate of the square tube-shaped shell is less than 80 degrees; the square tube-shaped shell is compactly matched with the left propeller and the right propeller, and a minimum gap between the left propeller and the square tube-shaped shell is less than 8mm; the left propeller and the right propeller can flexibly rotate in the square tube-shaped shell respectively under the driving of the left engine and the right engine, are opposite in rotation directions, and can mutually offset torque. Compared with a conventional ship thruster, under the same flow rate, the thruster is high in efficiency and low in resistance.
