So, as I've mentioned, I have rot and delamination in the transom.

I've drilled a bunch of holes and let the trapped water drain out.

I've injected CPES (Clear Penetrating Expoxy Sealer) into several places in transom. In some areas the wood was solid and would not accept any. In other place I could get a good amount in. In other places it looks like I pierced a void and was able to pump endless amounts in with little resistance eventually causing it to drain out the holes I had drilled in the bottom.

The drain hole fiberglass had separated by about 1/4" causing bilge sauce to leech into the transom wood, so the wood around and below the drain plug hole is saturated with oil. Prior to injecting CPES I had injected acetone liberally in the hopes that it might pull out some of the oil. I do not believe this worked.

After several days liquid CPES was still slowly leaking out of the bottom hole. I'm guessing the oil was somehow preventing it from curing correctly. I had mixed equal parts of the two parts and stirred vigorously for some extended period of time. Hopefully I didn't make a mistake with the CPES.

I used water-proof kneedable epoxy to fill in the gap around the drain hole. It seems to have made a solid seal over the crack. If water continues to intrude it'll split again eventually forcing some more permanent and correct repairs to the transom.

It looks like the water originally got in around the swim platform mount screws which were simple short wood screws. There was next to no evidence of caulk on them. The wood behind the mounts is severely degraded. Per Billy's suggestion, I through drilled the holes and used stainless machine screws with large washers along with an aluminum backing plate I fabricated to shore up the mounts. Installing these plates in the far corners of the transom on the inside is one of the more challenging jobs I've done. Obviously the aluminum will degrade over time but getting stainless plates back there would have taken too much time and the aluminum ones should hold. Everything was caulked carefully using 3M 5200.

I've also replaced the wiper arm that broke with a high-quality stainless one. Unfortunately it looks like the port side wiper motor has failed. The anchor light has also failed and I don't think it's the bulb. Those two items will need to be tracked down.

I will be bolting on the trim tabs in the next session using new stainless hardware and liberal amounts of 5200. I'll use the kneadble epoxy to fill the holes I drilled.

The deck has been cleaned and 7 coats of poliglow applied. While not perfect, it looks pretty good. The hull and sides have been cleaned and prepped and I'll start with the poliglow on that soon.

Then it's just a matter of replacing some zincs and the boat will be ready to put back into the water. I will need to track down the port carb issue and also install the Flo-Scan's but that can be done after the boat is in the water.

My hope/plan is to host a dinner cruise soon after the boat is operational.

That sounds about right.
