It is in nice, as raced condition and a very hard motor to find these says.  On a Mercury clamp assembly with a co-pilot system.  The rest I believe is original Crescent.  Never had it running.  Owned it for many years.  Turns over, not stuck.  The gear case is marked "Lee Dingman".  I have the original Crescent steering bar.  Looking for a serious buyer, not interested in trades.  Pick Up ONLY
