I don't think it matters much if your talking about old boats or boats that are going to be relatively cheap
to begin with. Fancy expensive boats probably will be an issue. If your salvaging the goal is to pay a lot less then market for it when your done right? Otherwise why do it, just buy a good one. My boat was made in 1964. It wasn't "salvaged" but it has had major repairs
done to it. Some previous owner had redone all the decks. At somepoint someone patched a hole in the stern, the wiring
has been redone, it is not the original engine
, the fuel
and water tanks
are not original, It's a 45 year old boat stuff happens to boats over the years you just have to fix them. I'm glad I don't have to redo the decks or fix the hole in her. They seem like they were done well, didn't bother me. I paid more for her today then the original owner bought her for new in 64.
