I've got over 200 hours on my 08 FX HO, and I have 2 friends with over 300 hours on theirs. Very rare for that engine to blow, but I do know of a couple of other cases that have been posted on the internet. Any engine that turns at 10000 rpms that is a possibility.
One theory that I've heard from a guy that works on these engines, is that if this engine is even slightly overfilled with oil, it can create excessive pressure that can cause a rod to fail. He told me that in this case it is usually one of the rear 2 cylinders that fail.
You would be crazy to repair it, since you can find really nice used FXHO skis for less than $7000 in good running condition. Maybe you can find someone with a trashed hull that would be willing to sell the engine for cheap.
