97 Waveventure 1100 locked up

[harm]

My wave runner engine locked up. I was going about 30mph when the engine just stopped, immediately. If i push the starter button i can hear the stater turn but the engine don't turn. The front spark plug has some gray(assuming aluminum) on it. This motor was swamped a couple of years ago but had a new top end in it. I am assuming the crank went out. What do you think??

Thanks in advance.
