Transom Fiberglassing

Question
Hello Ron and a belated merry Christmas to you.
Here is my situation - I have a 1968 28 ft.John Allmand that was orig. set up with OMC I/O sterndrives which have been removed for a Outboard transom bracket conversion (twin 175's).
The existing transom in the boat is tight as they come with no water intrusion or signs thereof. They really put some seroius glass into this transom at the factory. I recerntly installed a drain plug in the transom and found the double 1 inch boards to be as dry as the day they were orig set at the factory. I knowe this is hard to believe as having almost 40 yrs of hull and boat work under my belt  I realize the implications of making such a statement: realizing that NO hull is exempt from water intrusion, epsecialy a hull that has over 40 yrs of running time. Anyway...I say this because If I dont have to remove the whole inner transom then I don't want to.I have no reservation in saying the existing transom is Stout as they come.
My Question is where can I get a resource for specific instructions and line item step-by-steps on glassing over two stern drive holes with the proper integrity in preperation for a bracket set-up. Any direction would be greatly appreciated.

Thank you,

Answer
Hi Bob...thanks for selecting the undersigned to reply to your question. I'm not familiar with the manufacturer of your boat.

Without actually examining the project closely I'm reluctant to make any suggestions. I would recommend you consult a local & reliable boat repair facility for guidance.

My primary concern is the weight and stress that will be exerted on the transom once the twin o/b's are mounted, and how that will affect the areas of repair. It may not be as big a problem depending upon the type/design of the brackets used to mount the engines. Obviously, the integrity and strength of the repaired areas is extremely vital to ensuring a sound hull for safe voyages.
