Almost forgot we were waiting for these pictures.
Two more items:
- Do you trailer the boat with the engine on the transom ?
- Could you number the photos (lower corner) as it becomes difficult to discuss photos with so many presented as evidence ?
At first glance, the photo with the callout "motor mount stress cracks" does not cover enough of the interior of the transom to offer any real support for the motor mount. There will be some prep work and cleanup, but what you're finally after is, rather than two narrow sticks acting as backing you want two large area plates in the same location. The trick here will be to ensure that in between the plate and the transom is a spongy fiberglass cloth that will take up all imperfections in the transom. There is some question about composition so the larger the area the better. My lack of knowledge of cloth weights speaks for itself.
Perhaps another method is to fill the gap between plates and transom with Bondo. Maybe others have used this and can speak for its resilience around water.
This is a start and we can move on from there after you come up with a solution for this first area.
