I make these units on my lathe. They are made from 6061 aircraft aluminum and quality bearings. They come if different sizes for different motors and can be made to custom fit your application. The clutch shoe is made of a high strength neoprene rubber and is designed in a way that you can tune it to engage at the RPM that you want. The unit shown is on my cmb .67 which is to be installed on my dumas Miss Circus Circus build. I am currently offering this unit for $100 each. Additional clutch shoes are $15.00 each. I feel that this is a very reasonable price as the materials to make cost me about $25.00 per unit and about 8-10hrs to manufacture and test before shipping. If anyone is interested please reply. Again these can be custom made to fit your application.

If you want to build one like the real ones with the engine mounted in the rear, you would need a V drive .A guy who's screen name is 2speed on Model Gas Boats MGB Home and maybe other forums makes V drive gearboxes to use with either electric,nitro or gasoline engines. These are custom made for your setup.His email is [email protected]

The only issue with using a "V" drive is that, depending on the rules you race under, it's illegal to use any kind of gear drive. I know they use gear drives in Europe and, due to that, actually manufacture engines with a gear drives. In the US, however, I don't know of anyplace that run a gear drive set up
I've always wanted to get a Dumas 36" SK Daddle kit and trace the parts before I put it together and get the parts sheet enlarged to a nice size to fit a Zenoah 26 with one of his gear boxes. The 36" I'd get a 1/6 scale dragster engine and get an electric motor inside it with a gearbox. There was a guy on one of the forums who make them with electric water cooled motors in them.Hyperformance has the V drives also and aluminum tanks Aluminum Fuel Tanks

If you're going to use a clutch on a nitro boat for idling or short stops you should have a water pump.I had a Dumas Scarab 38 KV with an OS 77 VRM in it and the guy who built it put what looked like a windshield washer pump powered by a small battery. It was setup with a switch next to the throttle servo that the pump operated when going slow as this engine had no clutch and when you accelerated the servo arm shut off the pump and water was supplied by the water pickup on the hull.It also acted as a pump to remove water from the hull while the pump was operating. I never used the setup myself.
