Keel Made of Bridge Timber

Ah, I didn't mention that just the timber is that old. The boat's from mid 1980's.

But, what I'm worried about actually is that the structural integrity of the wood has been compromised through the process of pressure treating to the point where I have a keel with about half the structural properties of non-treated fir in a place where I think oak might have been intended. I'm quite sure I read somewhere not to use bridge timber no matter how tempting, but I can't remember where, and can't find the reference.
