Chris,
I have also seen people put various types of "wings" on the cavitation plates of their outdrives which can sometimes dramatically increase the wake-enhancing effect of the trim.
I got one and tried it but I think I got the wrong kind. I got an SE Sport 300 because I heard it was the best one. Well it is really great at getting the boat on plane faster, which is what it is designed for, but it is too narrow, and far back to work well as a wedge.
"SE Sport 300 Stabilizer" When I looked off the back of the boat while underway, the layer of water on top of the foil (the water that would be pushing it down) was very small. I think that using a different shape will help a lot.
I'm going to make an aluminum or stainless plate that uses the same hole pattern as the SE Sport. A little more like this one:
"Cobra Stabilizer" but wider and more toward the front...shaped more like the Doel-Fin below.
I think the ones I saw that worked better for wake enhancement were more like this one. Notice how much farther forward it sits. This makes it dig deeper into the water with the trim up:
