Flathead screws are indeed the absolute worst! There are few different ways to rebuild these hulls to make them last as long as they did. What you have to ask yourself first is what type of finish do you want and what your intent is with the rebuild. If your looking for a nice finish inside, the liner will make it much easier not to have to fair/finish the inside of the hull after you tie the deck into it. However, when you cut the deck out and try to leave the liner, you'll want to tie the deck to the hullside to keep some structure. This will leave you with a liner that has to be re tabbed into the deck  so it has to be trimmed (assuming the deck is thicker or at least will be raised). The last option that I don't believe you see often is removing the liner as one piece (hoping it doesn't crumble)..and recoring it filliped upside down with divinycel, coosa, or other composite materials Check out my flatback thread and you will see what I mean. There are a LOT of rebuild threads on here to look over and many proper rebuilds to follow. Share some pics and it will really help with guiding in the process and perspective to answer any questions you may have.

Thanks Rick!  You are a wealth of knowledge on this board!  Whatever it is, its too big for me to trailer!

Hi everyone. I have an 85 290 with 5.7s for sale. She's located in Center Moriches NY. Boat runs Very well. Last season she got NEW carbs, heat exchangers, raw water pumps, full exhaust, and a bunch of odd and end. She has a Solar charger that's not tied in, but is there. Windless, working fridge and stove. She has an older radar that's intermittent. She's wears her age well. I'd steam her 100 miles without thinking twice. I'm asking 8500. My cell is 631 786 0912. Ryan Thanks!

+1 for Petit and blasting. I got mine soda blasted. Good result. Barrier coat? Not sure if it'll need doing. In theory the existing antifoul should be considerably softer that the barrier coat, so it should be apparent if the barrier coat is compromised or damaged.

I think Ive a main tank leak. Hoping to get a poly tank to replace if possible. Anyone have the tank dimensions under the console ? TIA.
