I have a disassembled cylinder block that came with a boat i bought.Dude ripped motor apart and i got it in buckets.The cylinders and crank are all rusted but aluminum block seems to be in good shape.Can this block be saved or worth anything to someone,or just take to scrapyard?I already sold lower end,which paid for the boat.It's a V6 merc. late 80's.Any idea's would be great,specially if someone needs to replace a cracked block or somethin'
