Re: DualSync Waterline Drive, Update & Video

I would think just incorporating that transom style into a common boat would improve its efficiency by lowering the motor and prop like you have done. So the question is who will be building the hulls. I do wonder how the transom works how it lowers and how it seals water out. It does look sweet te...

Steve:

Pleasant close of last evening. I watched it several times and felt like I was flying again, then air boating over one of our many beautiful marshy lakes.

Great new technology used with your seasoned talents and great skill.

Re: Water Walker’s NEW Congo Cargo Airboat

I agree with white bear. And btw guys I really like that boat. Not asking u to have to go into a ton of detail but how do u keep it from leaking real bad at transom? Transom looks like it blows down pretty easy so it can't be closing too tight right?? Anyway looks great and good luck with it, love ...

Re: Turbo charged rotary???

you need at least a 74" to 78" prop. and it can hold 600 hp back. run a 2.9 to 1 box @ 7400.. prop rpm will be 2569. that should work good. or 2.55 @7400 be 2900 prop rpms. We are building a 2.4 ecotec that makes 600 plus hp with a 2.38 75"8 blade saber. its for racing Sure, 'hold back 600 HP." but...

Re: Turbo charged rotary???

Rotary: At a 68 " Diameter disc area computing 25.32 square feet, you are limited to about 260 HP for efficient transfer of rotational HP to thrust. For better understanding, you would readily agree that say a 36" prop wouldn't do you very well or a 24" one even less. So, 68" 'ain't' enough for 600 ...

I know many engines can be bought for less that even has more power. On the other hand, this is the wo...
