Yep, the rotation of the prop will causing the listing. It should be more apparent at slower speeds when the prop is trimmed down and digging in more. Usually as you trim up it will go away and run more level.
A hydrofoil will help some what on a boat that leans to the port side because the prop on an outboard is turning right handed and as the blades leave the water the spray picks up the left side of the hydrofoil causeing the boat to lean to the right, more noticeable if your alone and sitting on the starboard side while driving. Many times the boat will run straight if there is a passenger to counter act the lift from the prop blade.

Helped mine from porpoising and jumps right up on pad
My boat was a turd coming out of the hole onto the pad, I put on a Stingray and it did help with the holeshot. It didn't SOLVE my problem, but it did decrease the time to get on plane. My fiberglass full is extremly stern heavy and even with the front livewell full and all of my gear up front, if I have anyone fishing with me my passenger would have to sit on the front casting deck until the boat planed out. I ended up having to try several different props until I found which works best for my rig and now I can jump up out of the hole in just a couple of seconds. So I don't think the hydrofoils are a cure for anything, they only minimize a problem to the point of being tolerable.
I was having problems with porposing with my 16 foot aluminum with 40 etec on the back. The only way I could allow myself to trim up at all was with 170 pounds of sandbags stashed up in the front of the boat. Put a stabilizer on it and my boat shoots out of the holeshot like a rocket with out even raising up... Would of never thought a cheap accessory you could buy at Walmart could do so much good.....
My little 16.5 Alumacraft's console is at the very back of the boat with NO weight in the front. Add a 50 Yammy 4-Stroke, my 6'3" son and my big ass back there and you can guess what I looked like getting out of the water. On the maiden voyage I gunned it to get on plane and I thought Patrick was going to yank my arm off! I truly believe it was 50+ degrees trying to get up. It was so bad that Patrick sat on the front til it planned out then moved to the back. Big hassle. It's not the exact layout I wanted, but the deal RP @ Breaux & Daigle gave me was just too good to pass on. Besides, they're awesome to deal with on service.
Anyway, after a month of research and question asking, I decided that trim tabs were the way to go, but boy, they're expensive. Then I found these: Smart Tabs SXThe best price I found was at iboats.com for 99.00 and I installed them myself. Easy installation and doesn't leak a drop of water.
My little baby now planes at 13mph no matter how much weight is in the back and doesn't lean on the turns. That part takes a little getting used to, but it's like driving a Mustang GT on the water. The difference is that drastic.
I've since added 3/4" floor, some carpet, 2 ice chests, anchors and fishing gear so the boat is real heavy now, but I still get 10-11 mpg @ 5200 rpm and 34 mph. I ain't complaining. And no, I don't work for Nauticus but I highly recommend them to anybody who asks about them.
Hope this helps.
