Anyone of you guys ever heard of these? Seem like the cats a$$ of the carb world.

I believe Patrick has something about this carb and marine use and I don't think is recommended yet. Give him a call, he'll give you the low down on it!

I use their carbs exclusively...used dominator on top sportsman car which have since sold...had one done for the boat with a procharger blowthru...worked great out of the box..and many said they have issues with a blow thru...to drive my boat you would never know its a blow thru...getting ready to order another for a turbo blow thru set up on E85 on a drag radial car we are starting to put together..that being said, they know their stuff !!!
