Where there is smoke there is........
Oh boy, well my friend was driving the ski and it quit all of a sudden. She waited a few minutes, but saw smoke coming from the front and back. She was very frightened, but needless to say here is what i found. It poped the white reset button, and MFD shut off before hand. Hopefully MFD is ok, just got it from ph2ocaft. Your wisdom is welcome and appreciated

Well you need a stator for sure as I'm sure it's junk. you can send it to John at Jet Ski Solutions and see if he can repair it or not.
Look at ALL your grounds and pay particular attention to the ground cable at the engine. Clean the paint off the engine where the cable grounds, clean the cable at the engine and battery. Actually I'd clean every electrical cable I could find and access.
Hopefully the .25 amp fuse did it's job and the MFD is still O.K.

So the stator can just give out like that and fry those wires. I accidently pushed the reset button because it was dark and i was fooling around, and the wires were arching and more smoke out the front till about 30 seconds later the reset popped again. How much we looking at here. She ran great all day and then quit. this sucks. At least my XP ran like a crazy champ (sorry polaris dudes). I have a decent amount of water at the bottom. Not alot but couple inches. Could that have shorted it out. The day before I took it out I replaced all the exhaust gaskets cause they were leaking water a little. I threw it in the water but never checked to see if the leaks were still there or not. The stator is sealed in the front and it shouldnt matter, right?

I see that you don't have the OEM plastic Polaris battery cover.
Is there any chance that the positive battery post contacted the case of the electrical box during that last ride?
Look for arc marks on the bottom of the electrical box, near where the battery positive post is.

That battery looks very protected to me.
Let us know what you find on the electrical connections.
I left a message with Brian at Ultimate over the weekend and he called me today letting me know he has a used stator for the 780. I already ordered one from zig so I don't need it, maybe give him a call.

That seems to be a common problem. Don't forget to check the allen screws inside the elc box too. The voltage regulator holding screws are a crucial part of the elec system.
Stator may not be junk, you can replace the wires all the way back to the stator and see what the stator ohm tests out.
