Had a mini jacker on my little Grumman 1542 for a little bit. Yamaha 4 stroke 25 hp. Also ran a 11" 4 blade prop, no foil. No power tilt unless you call kicking the motor in reverse with the tilt unlocked "power tilt".
Reason I did it was because I sometimes run a river that is real wide, but a foot deep, or less, in a lot of places. Was dragging bottom sometimes. Rock/gravel bottom (no sand or mud or logs to speak of).
First thing I noticed with the jack plate was that I was able to lift the motor about 3 1/2", roughly, from "even" with the bottom. This helped immensely. Found a local guy who had a 4 blade Solas 11" that fit my motor, bough it, and that helped a lot too. Was able to get it out of the hole quicker. If it had power tilt, it'd be a little easier to deal with but it doesn't and I am not going to spend a ton of money on one that does. The 4 blade prop slows it down a hair, like about 1 mph, but I got that back-and then some-with the jack plate. On rougher water when the boat was "riding" the tops of the wake, I could occasionally look back and see about 1/4 of the prop blade tips in a blur, out of the water. It never blew out to speak of. One time when the GF and I were riding around and she was sitting in the very front of the boat (on the nose) and I had the motor tilted up to the first shallow water position and tried to plane it off.
Sold the boat, with the mini-jacker. If my current boat/trailer would fit in the garage with a CMC PT&T, I'd have one, but I don't' even have an inch to spare now much less 5 1/2".
Ran a foil on my old fiberglass boat. They work if everything's set up correctly. Out of the hole a little faster, little more stable when just barely on plane but that's all I really noticed. Took it off for a while to try it. Put a 17" 4 blade Solas on it and really couldn't tell any difference between that setup and the old Turbo 18" 3 blade SS with the foil. But I did lose a couple MPH. No jack plate. Tried one, in an attempt to drag race a friend's boat (which was bigger and 110 more HP)....3 blade 21" Turbo with a lot of rake and the JP helped a ton. Almost 6 mph improvement. 59.7 mph on a little 16' boat with a 1980's 90hp Mariner. And to end that deal, the reason I got rid of it (well one of the major reasons) was because I was running wide open down river headed to the ramp about 49-50 mph...to beat a barge and passed up a log that was, probably 3 foot diameter maybe 15' long, just barely under the surface, just caught a glimpse of it as I passed by it, no more than about 2 foot from the side of the boat. If I'd have hit that thing...not sure I'd be here to talk about it.
