we have a 2000 scorpion, with a 200 fitch (2000 model). When i did my research i found that older engine model had modifications but mine was a newer version with one modifications.
You can see from our running reports in the gallery (serch jimbob) that we have had no problems with the engine. I did however check the service records, good people kept a print of of the ECU and it can tell you if something is going wrong, as example i noticed that the temperature was well within spec but was rising. Also it seems to make a fuss about the correct oil and you can see if its been hammered but the revs readouts.
When i first got it and it was ready for a service i asked powertech to check out why the engine temp was going up a little each time, basically there was a bit of rubbish in the cooling system, since then its been great. As long as you service they run and run.
it did take me a while to get one with a good engine record, but apart from that as i say no issue, not sure if 175 is enought the 200 is OK for the work we do
Boatless - better get down the pub and drown my sorrows
