The invention relates to ship thrusters, in particular to a square tube propeller ship thruster. The square tube propeller ship thruster comprises an engine, a propeller and a square tube-shaped outer shell. The engine is installed on the outer side of the square tube-shaped outer shell through a support. The rotating plane of the propeller is perpendicular to an output shaft of the engine. The rotating plane of the propeller and the opening direction of the square tube-shaped outer shell form an acute angle. The cross section of the propeller is in an airfoil shape. The inner circumference of the cross section of the square tube-shaped outer shell is in the shape of a rectangle. The length of the rectangle is slightly larger than the maximum external diameter of the propeller, and the width of the rectangle is slightly larger than the sinusoidal product of the maximum external diameter of the propeller and the acute angle formed by the rotating plane of the propeller and the opening direction of the square tube-shaped outer shell. The propeller is completely located inside the square tube-shaped outer shell and can rotate inside the square tube-shaped outer shell flexibly. Compared with a traditional ship thruster, the sectional area of the square tube propeller ship thruster is much smaller when flow is the same, the efficiency is high and the resistance is small.
