Jet pump failure (continued)

When the jetpump failed back sunk pretty far down reaching the waterbox AND the battery. Here are pictures:

My question is how did so much have been taken on to reach that level just from the bearings being broken? Can anyone give me a deeper explanation?

If the pump bearing came apart for lack of grease....did the prop and shaft move around and kill your carbon seal?

What is a carbon seal?
