I have a 200 fitch
I think after 2000 any modifications that were required were built in,,i say i think, mine is a 2000 model and all was well
two things with these engines,
1) they must have the Evinrude oil
2) Check the service records, they usually come with a detailed printout from the ECU. Before i purchased the boat i have now, i looked at another 200, but the service records showed that the engine had used the incorrect oil and the ECU was slowly getting hotter. If all looks well then it will be OK.
I have run mine for just over a year now, if you look in the gallery i do little running reports,,,all its says about the engine is "as usual the engine was fine", for me its been a good engine and goes very well, we intend to use it for many years
hope this helps
