When I purchased my flounder boat, it had a poorly made compression plate(hammered edges) on the outboard, so I decided to take it off and purchase a new one. After shopping around, I didn't find much to choose from, and the one I liked was $345(ouch).
So I spent a couple of hours and $35 to make my own. Pics attached. After running it Saturday, I was impressed. It worked really well and kept the prop from cavitating at all. I think it needs to be moved a little further forward to eliminate a little too much water spray between the transom and the motor, but once it is planed out and trimmed correctly, the spray goes away.
I'll continue to tweek on it until I get it near perfect.
I'm considering building a compression plate and hydrofoil combination unit. Basically it will be a compression plate with wings. I'm hoping for no cavitation when running shallow with the motor raised and quicker plane times. If anyone has a shallow running boat they want to try one on, let me know. Hoping for a 115hp to a 150hp for testing. Prefer someone who goes out a couple of times a week. If you have a boat that cavitates alot when running shallow, you need something like this.
