My motor puked all over it's self!

Had a great day on the river with my two boys, my sister and my niece and nephew. We were tubing and just running around for a couple of hours. Well on the way back towards the boat ramp my motor picked up a bad knock, I slowed down and eventually it stalled. I pulled the heads off today to see if I could see anything, I did not see anything that caught my eye.

Somethings going on inside though, I can't rotate the flywheel all the way around, My buddy and I are thinking maybe a rod bearing or something. Whatcha think?
