Have someone weld a couple of 4" X 6" end plates on the ends of the angle and through bolt them to the sides of the transom well with some backing plates on the inside of the battery boxes. That should hold you until the fall and don't forget to trim the mushrooms off if the grow up through the crack - we have our "standards".
This is a common problem with two stroke outboard motors - they have too much torque. If you had one of them mild mannered, Mr. Rogers four strokes with the same torque as a hamster wheel you wouldn't have these kinds of problems, fer gosh sakes. Since that OX-66 will last you until about 2036 you, got some time to pick out one you like. By then you'll be old and OK with going slow.

Do this. Aluminum C channel will be far stiffer and stronger than fiberglass. It is what I did on my 20MA. It works great. I used 6063 alloy with radiused internal corners. I got away with 3 feet in the splashwell and two below deck between stringers. I am on year 3. I got a single 5 foot piece from McMaster (.com) and it picks up all 4 outboard mounting holes. I sealed it down with some 3M 5200. It is bulletproof figuratively, and almost literally.
Heavy underpowered 4 strokes make torque on the transom as they bounce on the trailer at 70 mph.
