The 21 eliminator with the quad rotor Chevy and the surface drive? Did they ever make that thing run or what....??
that was john sofilos at unlimited marine. Heis old shop was 5 minutes from my house, used to see him all the time. We talked many times about his conversion, but he changed his system many times, never fully satisfied with his creation. he is an incredible fabricator, w/ a ton of racing history. he did actually get one design on a 21' daytona, but unfortunately it threw a blade on a brand new tom black prop(nothing from the drive), and left a messy situation for everyone involved. Since that one, I dont know of any that have been completed.There was a guy that had an add in the back of hot boat. he had this surface drive that would bolt over the hole/cut out of a jet pump. It required a 12 degree transom, jet boat transom basicly. It was sharp looking. I talked to him a couple of times. The unit was priced right for a surface drive, around $3,500.00 at the time.
With the Casale box IN THE WATER, I don't see how it could live. The gears, bearings, and oil get hot under load and then you stop the boat. All the cold water would be attracted INTO the gearbox by the hot metal and hot oil. I'm not wrong, ask Casale. I've built custom surface drives and no CASH PAYING CUSTOMERS have stepped up in the past 25 + years to buy one. No one is willing to experiment with their money, they would rather "buy a proven winner" and just purchase Joe Blow's old race boat. I enjoy reading about all the new designs in performance boat hardware, but it's far and few between when a 'real performance gain' is achieved and the thing actually will LIVE. I do hope everyone KEEPS TRYING for that 'perfect drive unit'.Here's a pic of John's jet to surface drive conversion. When Steve (LittleJockoCougar) was discussing this for his kevlar 21' Daytona (with a no BS 1,200 HP blown 598) he was talking about $7,000 for the package (less prop). It's kinda neat cuz it simply hangs a Casale box outside the boat transom. I think they had the same problem as the Arneson drive on that new Daytona. It wants to drive the nose down and ride very 'wet'. I think it might work better on a smaller / shorter tunnel like a Placecraft. Maybe when $$$ starts flowing more freely someone will spend the bucks to experiment with it.
I heard the biggest problem they having to over come is prop walk.I heard at about 80mph they thing is trying to swap ends.This is coming from a ex eliminator employee i do not how true it is.The 21 eliminator with the quad rotor Chevy and the surface drive?

Or just put the right pump on it and enjoy it.......sphss It would be cool to see one work right but with the jets running 120+ I am not sure its worth all the hassle and $$$$$?I heard the biggest problem they having to over come is prop walk.I heard at about 80mph they thing is trying to swap ends.This is coming from a ex eliminator employee i do not how true it is.
I think somebody needs to come out with a drop box with one input shafts and two output shaft to run twin arnesons .It would fix the prop walk, and have two props for bow lift, and be bullet proof . Or just make things easy and run the new dual prop surface drive from weismenn (sp?)
