The invention discloses an underwater installation method of marine rudder system, which specifically comprises the following operation steps. Si. Pre-installation, wherein a rudder stock bearing sleeve is installed on the stem and a rudder stock lower stop sleeve is sleeved on the rudder stock. Besides, rudder blades are fixed at the bottom of the rudder stock. S2. Adjustment, wherein the levelness of the hull will be adjusted by adjusting ballast water when the hull completely floats on the water surface. S3. Hoisting. S4. Debugging. In the invention, parts are assembled in advance to form a preassembled body, so that the ship can be quickly installed after launching, thereby improving the installation efficiency of the rudder system. Moreover, with the water body in the dockyard utilized to float the hull on the water surface, the inclination of the hull is adjusted by ballast water, which is beneficial to keep the hull in a horizontal state. Besides, since the hull is inside the dockyard, it will not be disturbed by external water, and the hull will be more stable, which can reduce the level of installation difficulty of the rudder system. With a wide application range, this method can be used to install the rudder system of various ships, and it can also be installed on water because of its simple operation.
