The embodiment of the invention provides a cabin-entering hoisting method for a ship main propeller, which comprises the following steps: hoisting a main propulsion base of the ship main propeller, fixing a hoisting eye plate and a paddle of a propeller of the ship main propeller, transporting a steering oar module to a first preset position below the main propulsion base, overturning the steering oar module, and hoisting the main propulsion base and the paddle of the propeller of the ship main propeller; the method comprises the following steps: hoisting a steering oar module in place, installing a connecting bolt, cleaning a hoisting hole flange surface and a sealing cover plate flange surface of a main propeller base, installing a sealing cover plate, carrying out pressure test on the sealing cover plate, and plugging a pressure test threaded hole by using a screw plug after the pressure test is completed and no leakage exists. According to the technical scheme, the installation precision of the propeller with the large hoisting size at the limited height is ensured, the good effect is achieved, tool resources can be saved, the installation efficiency can be improved, and the construction cost can be reduced.
