A stern tube seawater inflow prevention device is disclosed. According to an aspect of the present invention, a stern tube seawater inflow prevention device comprises: a first sealing member located on the stern tube side; a second sealing member which is pressed in the direction of the first sealing member and rotates while making surface contact; a holder coupled to the second sealing member and pressed in the direction of the first sealing member; a housing coupled to the periphery of a shaft and into which the holder is inserted; and a pressure spring supported by the housing to elastically press the holder in the direction of the first sealing member. The housing has a cutout part whose diameter can be adjusted, and further includes a fixing screw for reducing a gap with the cutout part so that the housing is fixed to the circumference of the shaft.
