Need some help guys. Took the boat out yesterday was running perfect then all sudden boat stopped put it in netural and shut motor down checked everything looked good. Fired up the motor went put it in gear and it was very hard to do and motor would rev up wasn't in gear then tried reverse same thing. Thought maybe the shifter cable broke. Took the outdrive off far enough to check the cable all is good there goes back and forth as it should. So I then took the outdrive completely off the boat. When I turn the shaft in any direction the props do not turn. I'm lost on what to do next any help would be appreciated.
