Drivetrain not connected?

[CCme4skiing]

I was pulling someone skiing and all of a sudden there was a jolt and the boat wouldn't go anywhere. I shut it down and went underneath and the prop was pushed up against the rudder. I could push the prop / drivetrain back towards the engine. Prop and drivetrain seemed like they weren't damaged. It's a 97 nautique sport.

Anyone else ever have this? What did I damage? How can I fix it?

How does it look under the floor after the tranny?
