Fred Inman has done it again!!

June Powerboat(sorry) page 44. 20' Australian ski boat, 1100HP twin-turbo Paul Pfaff motor, twin IMCO Xtreme drives with a gear-splitter routed to the drives.
Fred just keeps the ideas comin'! idea

You mean like this.....?

[Catmando]

That's the one right there, burb. Notice the wing steering on the drives. Leaves like a jet boat and the twin drives cancel out the torque from big-power motors. No ventilation in high-speed turns because one prop is always in the water.
I was thinking about the Bruce Dualjet drive on my boat, but this system is very interesting also. The main issue is price; the IMCO dual drive is about $25,000, whereas the Bruce drive is less than $10,000.

I would NOT want to be in a 21' open cockpit boat at that speed. eek! Even 120 is too fast in that boat.

[schiada96]

so 140 in a flat is out of the question!!

[Catmando]

Well...maybe ONCE. wink I'm not a PUSSYcat, but I don't have a death wish either. 21' Vs are just not stable at those speeds.
I think, for a boat 28' and shorter, my boat is the best hull for 120+. Not to brag, but the Reverse Three-point hull has incredible stability and balance.

Sorry dude but your not thinking Straight. pig_flyi There is a reason you can throw a beach towel over everyone that owns one of your boats. It's because they don't work well enough to over come the unusual looks. I promise you most everyone would rather be in a 21' Cyclone ski race boat at 150mph than a Clastron. IMHO

RiverDave:
Is that he prime marine boat?
RD It was rigged by them, WILDERTHANU54 should have the skinny on these deals.
superdave013 was snapping pics of this at the Parker ski races.
