Failure analysis: Shredded outboard lower gear set

MBM20130801-202332-3279s.jpgThe outboard's back from the shop (Ward's Marine, Kingston, ON) and the lower gear unit is in pieces. Unfortunately, the damage is worse than we had hoped, and rebuilding with new parts would not be economical. Here's the story of what happened, as told by the shredded innards of the gear set.

Something's not right with this outboard...

"Kr-r-r-rattle-rattle-CHUNK."

It's not a sound you want to hear from an outboard engine.

The cause of the noise is shown in the photo. Can you find it?
