I need some help diagnosing a strange failure of a 98 GSX-L. Here are some pictures:





The crank had 10 hours on it when I purchased it. All bearings looked good and I rode it all season without any damage. The ski is ridden in brackish water, but religiously flushed and maintained. What is amazing to me is that the rust line suggests a significant amount of water (reguardless of salt content). I guess if the base gasket catastrophically failed, I could have pushed a significant amount of water into the engine when flushing. But that is a real stretch to me. I did notice some areas on the gasket surface where it is shinny, and some that appear to be blackened. But this appears on both cylinders (failed and good cylinder).

Any ideas?
