Looking to buy an old aluminum hull

If on a trailer, look for signs of pitting/corrosion if it was loaded on treated bunks.

Also an aluminum boat that old most likely has wood in the transom so make sure it's not rotten out.

All depends on the price and condition. Age isn't the issue per se, more that aluminum corrodes if not taken care of. That hull could be in better shape than a five year old one, just depends on if someone let it sit in salt, used dissimilar metals on it, etc.

Shape of the trailer is what would make the decision for me, the hull is a piece of cake to work on. Trailer parts are a pain in the arse to find and nothing ever fits right even if it's supposed to.
