This Crankshaft was removed from a Rotax 503 UL engine with just 119 hours  total time on it , The engine case and fan housing  were damaged due to a starter motor failure , The cost of repair was more than  a engine replacement  so I am selling the  parts with a total of 119 hours  on them since new  , crankshaft is true , tight  and clean with no damage and will have a six month warranty with it ,the BUY IT NOW price is $ 750 and that includes the shipping to you , thanks for looking .
