I searched for info about hydrofoils that help plane earlier at lower speeds
and learned a lot. But I have one question remaining. Does the hydro put
excess stress on the brackets holding an outboard on the transom? Can anyone
shed light on this? Thanks.

No, it's not a problem, or millions of boats that have them would be
experiencing transom failures. The industry standard is the Sting Ray
hydrofoil. It works great in getting you on plane faster, lowering your
minimum planing speed, reducing porpoising.
