The torqeedo prop is desingned to work at 1300rpm most efficient so i choose the gear reduction a little higher to get around 1500rpm. I'm not sure what the trust is but it feels like 30 kg. i dont know why i cant get more trust :( at full speed the multimeter shows me 4kw of power consumption...

when i started this project i also made some tests whit direct drive propulsion. i mounted a standard trolling propeller to the 80-100, sealed everything in a aluminum tube and taped it on a surfboard. the result was 3 burned turnigy 150A HV controller. But also whit my kelly controller the...

Finished my project... ilNCC6ttRO8

Yes thats right its a neugart plantetary gear (16:1). The hole electronic is hidden in the frame. There is only one plug coming out of the frame to conect it with the battery.

Hello sk8norcal, This one is also mine :wink:

kymera is absolutely amazing :D I hope so much to get similar results

some testing with the old jet pump http://www.youtube.com/watch?v=g4pnXOEGk0g&feature=plcp

There is a lot of potential in hydrofoil but whit my jet pump it is not so easy to realize this. There is already an electric hydrofoil out there.. http://www.youtube.com/watch?v=jh_RhkejWLw&pxtry=1

Thank you :D Cant wait to get this thing tested! Its really hard to tell how much trust to get out of this combo but your informations are really interessting! btw this is the pump I bought...

I bought a kawasaki 550 jetpump. I will test how much trust I get with one turnigy 80-100. My goal is to reach planing speed. Dont know how much trust I need to reach it? I think more than 200lbs..? Does anyone know how much trust a kawasaki 550 produce?

The jet pump dosn´t produce enought trust.. I will get one of this kawasaki pumps and hope to get more trust. One of my fist electric boards: http://www.youtube.com/watch?v=s9PRm23jXKs&feature=youtu.be

at Ratking: I´m really interested in testing one off this kawasaki 550 jet pumps! Also I will get alot more trust than now because mine only needs 55A to run at full trottle.. But my problem is where to get one? In germany I couldnt find one and shipping from the usa costs about 80$ :(

I couldnt test it.. still working on the surfboard.. here some progress pictures.

I´m going to test it today...

Hello, maby I will use one of this jet pumps in the future but first I hope to get this thing running.I also worked on a prop driven surfboard but there was no way to get planning speed begause of the friction caused by the motor.. so I desided to build a jet pump Ratking: Do you have detail...
