The invention discloses a marine winch. The marine winch comprises a waterproof welding base, a driving device, a speed reduction transmission device and a cable twisting cylinder. The speed reduction transmission device is arranged in the cable twisting cylinder, the speed reduction transmission device is fixedly connected with the cable twisting cylinder, and the driving device is arranged in the waterproof welding base. The output end of the driving device is synchronously and rotationally connected with the input end of the speed reduction transmission device, the output end of the driving device and the input end of the speed reduction transmission device are each provided with a pressure-resistant framework oil seal, and the pressure-resistant framework oil seals are in sealed connection with the output end of the driving device and the input end of the speed reduction transmission device. A newly-added seal structure comprises the pressure-resistant framework oil seal in the speed reduction transmission device, and the overall waterproof performance can be achieved without changing the internal structure of a whole speed reduction box. O-shaped rings and sealing gaskets at the static sealing position are simple and reliable in structure and convenient to assemble and disassemble. Compared with a conventional marine winch, the whole marine winch can be sealed under specific water pressure, a watertight housing does not need to be additionally arranged, and the application working condition is wider.
