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.

In order to lift the rear of the boat more there must be additional
upward pressure that is transferred from the motor to the boat at the
transom. So the simple answer to your question is yes.

But I have never heard of any cases where that additional upward
pressure has caused a transom failure. And imho in a properly
constructed and undamaged boat I do not think the additional upward
pressure would cause any damage. On the other hand if your transom is
rotted then it could be the straw that broke the camel's back :-)

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.

But wasn't the OP's original question referring to the brackets that are
part of the outboard motor, not the boat itself. I've had no experience
with these hydrofoils but was considering one as it takes forever to get up
on plane when I'm alone in the boat. Thought they might be quicker and
cheaper than a weight loss program.

Consider, rather than a hydro-foil...Smart Tabs, instead.

They lift the stern rather than the motor. I gave away my two hydrofoils
and replaced both with Smart Tabs. At $150.00 or so, ( at Bass-Pro-shops and
lots of other places) they are one of the best investments I've made to help
getting her up; planing longer; and riding better in chop. RG
