Rotax 503  provision eight  engine crankcase  , ITS NOT A PROVISION FOUR CRANKCASE  , It is  in nice shape  ,  low hours , I removed other components like cylinders , head , crankshaft  and ignition to sell  and have  the crankcase  for sale , The  Buy it now price is $ 1300.  which includes the free shipping to you  at the Buy it now price  only , ,  I had a person purchase this  engine case and he  contacted EBAY and  said  item was not listed correctly and  he got his money back from me right away  and  I paid shipping both ways  because  his provision four crankshaft did not fit into the provision EIGHT crankcases  ,,   SOOOOO    Look at the pictures  and make sure you kinda know what your looking  for  so I am not stuck again  with FEDEX shipping  BOTH WAYS   ,  AGAIN  ITS A PROVISION EIGHT CRANKCASE    ,    NOT A PROVISION CRANKCASE   ,   GOT IT  ???    Thanks for looking
