I had the cable replaced last fall and last week was the first time I had it on the water.It a 1990 16 foot Sea Nymph 161 fisherman side console,my buddy was driving it and the steering wheel came off the only thing was on the shaft was a washer no nut.I have no idea where I can get one I don't know if it is a left thread or right thread I think it is 3/4 shaft any and all help will be greatly appreciated. Thanks Art
