Why Are My Foam Filled Stringers Full of Steel?

I had this "ballast" in my 88' WA. My theory is the boats set up for a single outboard needed more weight in the stern.

I chiseled it out since I went with a bracket and 4-stroke outboard. There were 4 blocks, about 50lbs each.

Thanks, good to know. I figured it either had something to do with balancing out the cabin or the single/twin configuration. The guy that owned the boat before me was a water-skier so I was a little worried I was going to find that throughout the stringers and up end having to remove the entire thing. As is, I'll plan on removing and rebuilding the stringers as far forward as I find the shot. I don't think it would be practically possible to remove it without removing the fiberglass as well.

On a side note, there is less water in the foam than I would have expected. I've only opened up about 3' of one stringer, but if the rest of the foam is consistent, I'd guess there's less than 50# of water weight in all the stringers.
