Title: Can you separate the liners of the boat?
Post by: Kaczki on February 11, 2006, 11:40:16 AM: Is it at all possible to separate the top liner from the bottom liner on a 1971 19-1? If I could I would like to try that because my floor is soft in a few spots but I'd hate to chop my boat up.
Thanks!
Title: Liner removal
Post by: GoneFission on February 11, 2006, 11:53:32 AM: When you look at the old construction photos, it sure looks like this would be feasible. Remove the rub rail, sand/grind the glass tape bonding the liner to the hull, and probably remove some screws (most manufacturers use screws and glass to hold the halves together). You could then remove the liner, turn it over, and work on the bottom side...

Post by: JimCt on February 11, 2006, 03:35:44 PM: The hull and the inner liner were screwed together with ss screws 6" on center. The rub rail was screwed to the hull with 1 1/2" ss screws 6" on center staggered 3" from the other screws. The transom wood core was glassed to the hull before assembly but I don't know if they applied resin to the transom wood core mating surface when the liner was dropped in. If they did, then the liner would have to be cut at the transom corners in order to remove it. If the liner was not bonded to the transom core then the liner should be able to be removed with no cutting.

Seems to me that floor & transom rebuild jobs would be made a lot easier & faster by removing the liner.

Maybe someone who has done the traditional method transom rebuild could fill us in if he found the liner bonded to the wood core when he cut the liner away.

It's bonded now, that's for sure. That I remember.

Post by: Capt. Rick on March 15, 2006, 07:37:28 PM: My 22-2 liner was put in with bondo from the top down about three inches. I took one of those small nail remover/crowbars and slipped in between the liner and hull then used a hammer to chisel all the way from the front step up to the back. Took about thirty minutes. Faster that a sawsall and less chance of going thru the hull. Once I had it out I was able to grind off the junk. Have to admitt I thought I was going to split the hull any second but figured I could fix that if it happened. :idea:

Rick, man has your boat come a long way!!! 8) I wondered what happened to you and how it was progressing - wow!!! Looking real nice.

Post by: Kaczki on April 20, 2006, 04:45:47 PM: Any guesses about how much it weighs?

Post by: anclotelife on April 20, 2006, 07:38:38 PM: I was just wondering what you are trying to get by taking the cap off the hull? I have taken my inner liner off of my old mako. To tell you the truth Im not sure if it was worth it now. I mean I can get to the wash boards easier but that is the only advantage I have gained in doing so. So again I ask what you plan on getting to?

Post by: anclotelife on April 20, 2006, 07:41:51 PM: This is how I did it to my mako. I chiseled the edges as my friend lifted it with the forklift.

Post by: Kaczki on April 20, 2006, 09:21:37 PM: I was wondering if I could take the liner out, replace the plywood under the floor and in the transom, then glass it all back together. I hope that I don't seem like a total idiot in asking this but I think that doing it would save a lot of glasswork. So pretty much what I am asking is can the liner be reused after I take it up.

Post by: JimCt on April 20, 2006, 09:30:09 PM: Most of the work in getting the liner out is unscrewing the liner from the hull. There are screws every 3" but it is definately do-able. You'll have to have some way of lifting the liner out without stressing it.

Post by: Kaczki on April 20, 2006, 09:51:25 PM: Jim, do you know how the floor is glassed in? I know you have some literature on how Aquasports were built and I wonder you have something that talks about how the floor is glassed in. If there is little glass holding the liner down it should come out with very little trouble. If there is a lot of glass, well, :evil: :evil: :evil:.

Post by: JimCt on April 20, 2006, 10:30:54 PM: The floor, or deck (let's keep the terms correct here), rests on the hull stringers. On my 240 the factory dribbled a little high density foam on top of the stringers for bedding and lowered the liner down onto the stringers. You can see the remnants of the foam on the stringer...

(http://i24.photobucket.com/albums/c8/JimCT_/240_41.jpg)

When I cut away the deck it was not bonded to the foam at all; the foam just acted as a support. You should have no problem lifting your liner off. Only place the liner & hull are "stuck" together is at the transom. There you'll have to grind off the epoxy putty on the outside of the transom just below the cap. The transom cap is part of the liner. On older boats which still have their original transoms you'll most likely see a slight crack at this joint area. If the boat is still "factory" you can pull her apart in the reverse order she was built.

Post by: anclotelife on April 21, 2006, 05:46:56 PM: I to was wondering how to attach the cap back to the hull. I asked some glass guys in the area here, if I could just glass it together and not screw it together and they said yes but it is a lot of sanding and fairing to get it staright again. So in that Im under the impression just screw it back together and be done with it.

Post by: JimCt on April 21, 2006, 08:16:23 PM: Be easier on the next re-build in 20 or 30 years if you use the screws.

Post by: sandbarbilly on June 07, 2006, 11:18:23 AM: When you all talk about the liner I wondered about the deck cover (floor) of the boat. After numerous small repairs on my deck liner I've come to relize that it is just a liner. Doesn't seem to be bonded to the wood deck underneath. I could be wrong and the water soaked wood may have released from the fiberglass, but I don't think so. Boring a few holes in my transom for transducer cables I notice the transom liner is floating away from the wood transom core lower on the transom, which makes me think this is not bonded either. I don't think you will get the transom liner out clean. Some serious chopping is probably required to get it out, which means more repairs when reinstalling.
