after a lousy day on the water the other day I was putting my boat back on the side of the house. I lowered the wheel stand and started cranking it up to get it off my hitch. As I was turning it suddenly started to spin fast and obviously broke. I took the cover off and there is a little cotter pin style piece of metal that holds the handle to the gear inside the housing. Anyone know the name or where I can find a replacement pin to push back in? or am I out of luck and have to replace the whole thing?
