Transom rebuild outsid skin bad
 

Well i'll need some input on this one. I've done a few transomes from the inside but thats with keeping the outside skin in tact, tha shape, finish and integredy intact. This is dfifferent for me. The inside skin is good and intact. The core is gone obviously. It was saturated and froze so it split the outside glass, eeks. My concern is getting it back to shape and getting it blended into the sides and bottom with the correct strength. Should i leave the inside and gut out the core from the outside? Then adhere the new core to the inside skin and then glass the outside to the core? Or remove both skins and sttart from the outside and work in? Maybe leave a 2" section of the inside skin? Just thinking about tabbing the outside new skin to the inside of sides and inside of bottom for strength before adding the core. Core being Marine ply. Any pro input will be helpful. Not a professional fiberglasser for sure but have done a few projects. Transom outside replacement is new to me, thanks. I have some scary pics to put up to see what i mean. Shame the rest of the boat is solid. see pics.

Yeow! :o

Hermco, haha that was my reaction too. Must be why i bought the boat right huh? Oh well i've seen worse on here with complete transoms cut right out. it's a saver. One way or another.

Here is mine I started from the inside and worked my way out. Was not planned that way though

Nice build threads Entourage and fdheld, thanks but both jobs you were able to leave a small lip around the outside edge to keep the form and strength. Mine is cracked right to the corner so it makes it more of a challenge to me. The corners are the strength and form so to redo the corners the right way is where i need some pointers/steps before i hack the inside away, maybe i should leave it intact. But if i do that i wont be able to tab the outside new skin very far into the sides or bottom for strength. Actually yours Entourage is pretty close to flush at the bottom isn't it.

That looks like a perfect example of how NOT to rebuild a transom.

Forum member Shine rebuilt an Aquasport 222 flat back a while ago. He had a very interesting approach to his transom rebuild. He used a sheet of melamine board as an outer form to lay up his outer skin and then laminated his core from the inside. If I was in your shoes, that's what I would do. His build thread on Boat Builder Central.com was converted to a tutorial here:

The transom rebuild is on the first couple pages. If you go that way, you'll want to use a good mold release on your form. And personally, I wouldn't use his approach with anything less than epoxy resin. Polyester might work, but the superior secondary bond of epoxy would make me a lot more comfortable.

Boat is obviously un-fixable, I will be glad to save you the trouble and dispose of it for you. :D

Something does not look right. In photo #2 it looks like a skin was placed over the original transom. The old transom appears to be peeking out from under the transom skin.
Or is that my eyes playing tricks on me.

Agree. I dont think there was matt used in the original layup. Seems my old 20 was all roving. Is this a previous (wicked poor) repair that failed?

Has to be. On all the years I've been on this board I have never seen a seacraft transom look so terrible. :) I dont think that is possible with a factory built seacraft.

hiliner- Don is heading to Fiji and need a good boat once he gets there. You may want to give it to him in trade for something like a bracket :) You are in for a lot of work
