I was moving my 1983 catalina36 #99  across lake Pontchartrain and the propeller fell off  or quit rotating
any way I had  the boat towed to my new slip in Slidell LA.  I need to get the parts to replace my folding prop.  Universal mx25   I still have my old prop but diver wants shaft size , nuts and Key before he goes in.  I have to give up windy conditions from a back surgery last year and cant give up the ship.
