R1000 Inboard Hydro's

[Stuart]

Guys,
I know there are a couple of Hydro racers running 1000cc Motorcycle engines in R1000 class Hydros in Europe does anyone have any experience in this field I am intrigued as to how the driveline is set up, do they run a slipper clutch or special gearbox or just a converter to take the power off the former chain sprocket drive. The power to weight ratio of these plants is a massive bonus but how do they harness the power and what type of couplings are used to deliver the 10,000rpm and 120bhp from the engine. I believe they commonly use Honda Fireblade and Yamaha R1 engines. There is only one
R1000 class hydro running in UK as far as I know and that uses an adapted seadoo engine.
Many thanks

I dunno about the hydros, but,

I'm scaling down plans for a 12'6" Cracker Box using a 600cc Suzuki Katona motor. Direct drive, engine oil cooled, turned sideways, rubber shock bushing between the driveshaft and old sprocket mount. Clutch still hooked up, so, if it goes too fast, just shift down, or idle in N if you need to.

The cool thing...14,000 RPM in box stock form, engines are very cheap, cause of the geniuses who want to play Sport Bike extrodinare and end up with 100 MPH trees jumping out in front of them. Ever see one pass you on the road at 80 MPH on it's back wheel? My engine was given to the cause, but you can get bikes with less than 1000 miles on them for well under $1,000

The boats gunna be more of a big person toy, but if KTDoodle wants to take it out with one of her friends, she can.

Sounds like your Gonna have fun the Crackerbox will have a whole new lease of life and also give a new lease of life to all those Sportbike engines that managed to miss tree's!
