Outboard hydrofoils

Wanted to see what everyone's opinions/experiences were with outboard hydrofoils. If you think they improve performance, why did you decide to add one or why you don't have one.
Looking at the StingRay Starfire for my 70hp Johnson on a 17' Logic CC.
Appreciate any feedback.

I'm interested in this as well. Does it work sort of like trim tabs?

I added the Stingray Classic to my 90hp Evinrude and I definitely noticed a difference in both "porpoising" and getting up on plane. I don't know that it helped with fuel consumption but I suspect it has.

I added them a couple of times to under-powered boats. Helped with getting up.
Might help. Cheaper than a new motor.

Thanks for the feedback, and this is the no-drill version, so if I try it and it doesn't help or even hurts performance I can take it off with no damage to my lower unit and I'm only out $80.

I put one on an old tri-hull ski boat with 115 hp mercury years ago. It helped getting a skier up and on plane.

It's good for underpowered boats. Anything that's powered right I wouldn't put one

This...
For an underpowered boat, it can be a godsend. It will help you get up on a plane which in tough conditions is priceless.
If it's powered and propped correctly, it can hurt your top end speed.
I know lthey advertise fuel economy but from experience...it's only true in very limited circumstances.

I had one on my skeeter when I bought it because the dumbass before me didn't know how to drive it. He said it was the only way he could get it to stop porpoising. I took it off and threw it in the trash

I've seen it help on a boat that had a short shaft motor but needed a long shaft.
So IOW, yes it helps in certain situations.
Drilling holes in the cavitation plate isn't all that big of a deal. If you decide to take it back off you can fill the holes with JB weld.

Well then, I don't need it.

I use a permatrim. It helps keep the boat on plane at a lower speed. Perfect for how I use my boat. That's about the only benefit mine gives me. Plus it a fast repair for a smashed cav plate.
