My brother is looking at buying a leftover new 2003 pro-x 800. He can get it for $6500. Does anybody out there know anything about these 2003 Pro-x sleds? He would like to know the good and bad experiences that people have had before he buy's. I know that there is service bulletin S-03-06 about the ignition timing retarding at too low of a water temp. Can anyone shed some light on this for us? Thanks in advance.
