Looking at buying a used low hour fresh water set of cmi. Looking to see which were the bad years...they have been presure checked & all is good
Thanks

Many threads here on OSO on this subject and from what I can draw from them and the comments of many is that apparently years 205 thru 2008 are sometimes a particular problem, but who knows. Its really your call and it appears to be a gamble.
