Just wondering if anyone on here has one of the new 250 4 strokes. I have a 2009 250 pro xs 2 stroke that dropped the #5 cylinder last Thursday while running. My mechanic quoted me a new "long block" with hardly any warranty for $12,000 and would take close to a year to get. They then quoted me a new 250 pro xs 4 stroke with a 3 year warranty that I can get another 2 years of warranty for $1,000. Just wondering how people like these engines and if there are any known problems because I'm just a little hesitant about an engine so new to the market.
