2000 stx di 1100 New SBT Starter , Flywheel not rotating

[Vrodcp]

Have my Stx that When I hit the starter button it will just zing.
Things that I have checked
pulled Plugs to make engine turn over by Hand.
pulled the crank sensor rotating engine you can see movement like it should be
pulled cover off top of engine to turn motor over
removed starter using camera to see inside, when turning motor over by hand flywheel is not moving.
this is a very nice & clean Ski with only 97 hours on it .
I have checked and tried everything I can think of Any Help will make my Day

I would pull the front of the engine apart and check for a sheared flywheel key way or a broken crankshaft.
