Next step is pull up the entire bottom of the transom, clean, re-glue. Oh yeah, also put on the mini-jacker and got it up to 5". Seems way solid but I am concerned about rolling it up. I think I will have to make a canvas cover with padding for mini, jacker.
Did you clean around the patch with solvent? It looks like a professionally done patch...well done!
The bottom of the transom is glued. Only the port and starboard sides are welded.

No glue...when the plastic melts, it also acts as a sealant. It is suspectible to rot though from the top (i've had people set boats upside down in the grass, and the top edge of the wood wicks water up it) and the bottom (if the water sealing patches on the bottom aren't maintained, then water wicks up the bottom of the wood under the glued PVC section).
I checked my box of goodies...I actually have a little piece of transom as a demonstrator to show you how it works:
