Ok, so I hope I corrected my photo problems, and edited the last few at the start. Let me know if they show up.
After removing the old thru hulls, and seeing that the transom was indeed fine, I found these from Gem Products.

I did have to open up the transom holes, as these were larger. I also cleaned and sealed the old holes for the scuppers, then the new thru hulls with internal scuppers also covered them, so double protection. That hole above the Gem thru hull is for the swim platform.
