Shouldn't be any different than an O/B tunnel if set up right. O/B tunnels work very well. Instead of trying to work with a wing I would play with the drive angle.devilpardon my ignorance, but wouldnt a tunnel design try to pull the prop up out of the water as well? sphss
That looks like the boat that I bought from Eliminator in I think 1978!
When I got the boat is had the name Breaking Wind down the center of the deck.
The v-drive had a 1/2" mounting plate and was cut for big gears.
I put a mild 427 in it and it did not work well. I ended up parting it out and the guy that bought the hull was going to put a outboard on it.
