Looking at a 19' Stratos with a 2000 Ram Fitch 200. I've heard bad rap on the fitch engines , but may be willing to take a chance on this boat. Anyway too determine if any upgrades have been performed thru the serial#. What kind of maintenance issues would i be looking at. Been used to running a 225 EFI that was bulletproof and not very familiar with OMC. Thanks ahead for any help. much appreciated.
