PURPOSE: A centrifugal casting mold for a marine screw propeller is provided to form a more dense structure in a pressure surface of a screw propeller by rotating clockwise or counterclockwise and reduce casting failures. CONSTITUTION: A centrifugal casting mold(260) for a marine screw propeller comprises a lower mold(261), an upper mold(262), and a molten metal feed hopper(264). The lower mold is detachably installed on the top of a mold base. The molten metal feed hopper has a space for casting a boss as the shaft of a screw propeller. A space for casting a blade as the blades of the screw propeller is formed at a pitch angle to connect to a side of the boss casting space.
