I am trying to sell my boat and am hoping i get some tech advice. It is a 70 hp evinrude outboard 2 cycle. My wife hit a rock causing the aluminum propeller to bend one side slightly. It made the boat vibrate of course and we limped it back to the dock which took about twenty minutes and have not run it since. I had someone want to buy it and he took it to "his" mechanic to "go" over. I am being told that the prop caused the shaft to bend and replacement and labor to repair will be around $1700.00 which my buyer will conveniently take off the selling price. Is the quote sounding legitimate or do I need to bring my boat back home? P.S. I dont know the guy but it is a boat dealer that is quoting the repairs.
