The seawater-corrosion-resistant propeller gearbox comprises a shell, an input assembly and an output assembly. The shell comprises a shell body, the shell body is provided with an input cavity and an output cavity, the input assembly is arranged in the input cavity, and the output assembly is arranged in the output cavity; a metal reinforcing lining piece A is arranged in the input cavity, an input side bearing is arranged at the front end of the metal reinforcing lining piece A, and a driving bevel gear is assembled on the input side bearing. A B metal reinforcing lining piece is arranged in the output cavity, an output side bearing is arranged in the B metal reinforcing lining piece, an output shaft is assembled on the output side bearing, and a driven bevel gear is arranged between the output side bearing and the output shaft. The shell further comprises an end cover. According to the propeller gearbox, the shell is made of plastic, and the metal lining piece is arranged in the shell to prevent overheating deformation. The invention further provides a maintenance method and a manufacturing method of the shell of the gearbox. According to the maintenance method, the use cost is further reduced. The manufacturing method is easy to implement, and the manufacturing cost can be controlled easily.
