Be prepared for several new questions coming in the next few weeks. I went to install the flotation in my floor yesterday and decided to check my transom for rot. Tap Tap..good, Tap some more...good, Tap again....like echos in a cave. It's that dreaded hollow sound, the kind that makes you sick. This boat is to damn old to fix (1961 Crestliner) so I'll be picking up a newer hull and transfering my power to it in the next couple weeks. BEFORE I buy something I could use any advice available so I don't end up with more crap for the dump. I know to check the transom (now) but what else should I be looking for? Do cracks in the gelcoat mean structural problems? Is there anything I can look for without disassembling a boat I don't own yet? Thanks to all here for the help with my motor. At least I found the transom problem before someone got hurt or I lost the evinrude.
