Transom replacement

Started the transom replacement, pictures speak for themselves:

Its a 73 center console. I leveled the boat out. De-rigged and removed the console, rub rail, and unscrewed the cap. Lifted the cap, cut across the inner liner and separated the inner liner from the outer liner using a wonder bar. Pryed up on the flor and popped the inner liner up and out. The Transom is toast and I was able to remove most of it by hand, literally. Just got the epoxy resin and glass. Im gonna start laminating and will post more pics. After the transom then the stringers.

That has to be the worse transome I have seen yet!! :o Looks like you will be doing stringers and bulk heads also!!

Good Luck!!

Oh, plan to install inspection hatches in various places or make a drawing of ribs and runners in case you want to spray foam.

It's toast. Buy my Formula 20 footer with a huge cabin and start over.

WOW, another hardcore transom guy here. ;D
Its a mess, but dont give up. Will look better once you get her cleaned up.
Question: in your first picture, look like you can slightly see the cap...???is the cap still on ?????
Word of advise, some may disagree. A top knotch fiberglass guy watched me as I redid my transom. Everything went well, but when I went to put the cap on, somehow the transom got twisted out of shape by 3/8" to a half inch. I personnally think I should have put in three seperate peices of wood instead of one piece of wood covering the whole transom. The fiberglass guy told me, the strenght isnt in the wood, but in the fiberglass...and fiberglass is stronger then steel.
So, maybe if I would have pieced in the transom, it wouldnt have become slightly twisted. Actually, thats how wellcraft did my transom. Using three pieces of wood and not just one.
Either way post alot of step pictures or the rebuild. ;)

Yes, transom, stringers, bulkheads, the whole shebang. Actually the srtingers are not rotten, just delaminated, so I will re-tab those in and add some knees in the transom area. Replace the bulkheads. The floor core is good as well. The rest of the hull is asthetically in great shape and that is why Im bothering to fix it.

I was careful levelling out the hull and have been taking measurements to aviod distortion. I popped the cap up to get out the liner I cut but then popped the cap back on and threw in some screws to keep the hull shape together. May be unnecessary.

As for the transom core Im undecided. I am going to get 1/2" ply and cut it to shape, 3 pieces. See how easy it takes a bend and go from there. If it looks like its putting too much pressure on the hull I will cut it into three sections and scarf them in. That is what was there originally.

Sounds like a plan. Or run the saw down the wood, like an 1/8" to give the wood more flex. ;)

I cleaned the surfaces with a grinder, and cut a template from cardboard. Ill post some pics, hopefully I can cut the ply and start laminating this weekend.

Does anyone know if its OK to use stainless deck screws, leaving them in the wood as I laminate? Im hoping to screw the plys together as I go but I do not want to worry about taking them out.
