Clutch won’t disengage completely

Last weekend riding I sunk my rzr 800s in a creek completely soaking my belt and clutch . It started slipping on me so I drained all the water and everything seemed ok for the rest of the day .

Finally pulled it out of the garage today to wash it and put it in gear and let off the break and it starts moving with no gas also if I hold the break in gear it will start making a terrible squeal . I am no genius but it seems like the clutch is not disengaging as it should . Pulled the cover off the belt /clutch cleaned it with compressed air and it is still doing the same thing ? Any advise or suggestions would greatly be appreciated. There is no way I am taking it to a dealer near me , so I gotta do it myself
