Found a dingy that will suit I’m going to give it a go,
What do you all think it could work?
Check it it has v queel/bottom, that would make a big difference in stability
So I got this figured out, maybe this will help someone at some point.
Once I realized it, it was pretty obvious.
The air got pulled through the tube I had my motor wires go to the top of the board.
Once the pressure got high enough this sucked air right to the props.
If you need a hole in the board, do it behind the props.

do you have the files for those 3 bladed props (or an link to the thread)? could not find them here on the forum.
Interesting video of a scale model

Hi all, Not sure where to post this but I have an issue with my setup with my boogie. I have Bremote Rx and Tx wire and paired ready and working, the only issue is One motor is constainly beeping as if its not bound the other motor works but after I press throttle it starts spinning but doesnt stop at about quarter throttle, any help is much appreciated Its been a long and slow project but I can see the finish line and get it in the water
With a nose like that, my tow boogie would work like a submarine.
Even with rocker under the front section
So my version of the tow works “ok” now.
But the performance is currently limited by the nose of the board rising with speed until I get ventilation at the props.
Has anyone ever tried to attach some sort of miniature foil to the front of the tow, with the profle pointing down, like a stabilizer of the regular foil?
Have you considered shimming the motor mounts so the bow doesn’t climb as much?
Yes, I tried that.
But did not notice any real difference.
Maybe I will try again next time.
The time I tried that, I had some other issues as well.
Was just thinking how a foil might be perfect, as it would apply increasing downward push with higher speed.

I am just trying to imagine how shimming the mount will actually work.
You shim it in a way that the props are higher than the middle line, right?
So the shim is thick in “front” and thin in back?
But if the motors are behind the pitch turning point of the board, that may actually do the opposite of what I need.
Wouldn’t they add a downward force pushing the tail down and tilting the nose up?
Or do you shim the other way?
Think of it as working like the trim on a motor boat.
If the prop is tilted upwards the bow rides high. If neutral the boat rides flat
If tilted past neutral “down” the bow rides low.
Putting a foil in the water at the front would logically increase drag - battery use.
Maybe a spoiler on the front that takes effect when the board is moving at a good clip😉
Mark from Zerotow proposed a small update which I would take in consideration to improve nose down and avoid bouncing.
To stick on the back of the bottom
It’s cheap so worth a try !
OK, so it is the exact opposite to my picture above?
(Ok, I realize, it is impossible to understand what I was trying to show. Bow of the boogie is to the left, so the front of the mast attachment was lower than the back.)
Explains why it did not feel any better at all 
Thanks!
Yes. The prop thrust is directional so pointed down would “force” the rear of the boat up and therefore the bow down. If that makes sense. 
This prop “direction” might not be the problem as some hull shapes are conducive to a lot of upward lift so the boat has a tendency to “fly”. If your “boat” is a flier then shim for downward thrust will make things worse as you will have lift at the bow and stern.
I like the trim tab idea as it would be relatively simple to try.
