I am looking to buy a new (USED) engine (SINGLE) for my 20 CC. I am looking at a 1999 200 HP Evinrude FICHT with approx. 350 hours running time. No repair history. According to the owner it runs perfect. It is a counter rotating engine (will that be a problem?). The compression is good. Any advice to help me make up my mind will be greatly appreciated. $4,000 is asked.
