So, a buddy and I were talking -- he said I wasted my money on trim tabs.
I
said I did not.

The conversation revolved around the use of whale tails (foils on the
cavitation plate).

I said that they could help; but would add stress to the outdrive, and if
something that simple really helped, manufactures would make their
cavitation
plates larger.

What's the general opinion on them?

Our 19 ft CC with 125hp I/O (no power trim) has a Stingray hydrofoil, and
without it, the prop cavitates very easily in a high power turn. A bit lower
planing speed and less bow rise with it, but the reason I keep it on is
mainly cavitation prevention.

I would suspect that the angle of your drive in the turn and prop
selection has more to do with the cavitation problem than the plate.
