Thought I would start a new thread on replacing the transom in my 37" Active Thunder. I bought the hull 3yrs ago knowing it needed attention, just realized how bad it actually was. Apparently, it appears that sealing any holes was not on the list of things to do. It appears the transom assemblies and tab mounts to the hull were sealed with 5200. Anyone have an idea on how to remove them without ripping off all of the gelcoat? Heat? Torch? I have tried prying and pulling but the whole transom looks like its coming off with it.
All input welcomed, thanks

Holy phuck that’s bad,and people bust on Fountains lol
dont care what anyone says,I have worked on cigs,outerlimits,Baja,Powerquest,etc ,,,all the same $hit,

To answer your original question, I would heat it up with a heat gun, some scrapers might help,use piano wire and see if you can cut through the sealer once warm,Also you can use wooden shims ,heat it up and try tapping the shims in between

Lol, I know what you mean. I have an '86 Scarab Panther "Wellcraft" that I would have bet everything on that would be my first transom experience. The Panthers transom is solid as a rock.
The AT's transom has absolutely no wood left in it. I guess it should be easy to remove.

There are products that make 5200 “release”, I forgot the name... I score the 5200 with a razor and spray, repeat and slowly pry the parts with wedges.

May be others, but I use Debond. Not cheap, but definitely works

Yes that’s the one!

Well I had a busy day. I found the best tools for removing tab mounts and transom assemblies (3m 5200) is 1. a triangle brick mortar trowel 2.a painters tool, 3. a hammer and pry-bar. The brick trowel has a raised end that you can hit with a hammer and drive it in. Work it back and forth to cut the adhesive. I had to work all around the mount and transom assy. The pry-bar and wood (large surface area to displace the load) worked great to open it up and drive the large screwdriver in to keep load on adhesive.

It appears the transom assemblies have seen water for years.

Sucks now,,but when you’re done you will know it’s done right,,

So, wood choices? Red oak, maple, poplar? Grades? These 2 have perfect sanded finishes no knots $28-$55
