Of course anything can happen, but from the experience I've had with my YM1700, its so seldom one needs parts, it not much to worry about. I'm sure the small parts, that one may need, wouldn't be hard to get. We have some dealers on here that can get most anything we would need. And I don't know, but probably some of the parts for the YM's would fit the F and FX's. The are still Yanmar, and probably use some of the same parts. But they all seem to be pretty well built.
