flat bottom with inboard jet

How would I create a M or W shape in my boat?
I'm still thinking a reverse tunnel would do the job of gettting the intake to be the lowest point.

 

Please see the plans on this page for a few ideas

All I seen was some little fiberglass boats with outboard props.
I appreciate the help but that's kinda like comparing apples to horse buggies.
I am not an engineer but I can fabricate and follow direction well but I need to find a good design that can be adapted to my flat bottom aluminum boat.

 

I have made a few rides with flat bottomed jets as the OP means. Rivers smallish lakes and rapids it works fine. Draft was about two inches at full speed so no stones stopped nor slowed the thing. Be careful with sand banks or even worse if gravel..
