So you are going to test both?

I don't think that you will lose any performance, bec the layer is so thin. You have to make sure that the plastidip won't cause any contact and excess friction between the parts, then it will be OK. If you want extreme waterproofing spray then try this...

v8/p850 has 10 inch pitch, v19/p4000 has 12 inch pitch. I don't know the high speed (v30/p4000) pitch. but with the v19/p4000 at 1300rpm you should be going 23.77 km/h (without any losses) 12 inch = 0.3048m 0.3048m x 1300rpm /60s = 6.604 m/s = 23.77 km/h And here you can see that max speed...

I Dont know about pitch, but the high speed one is 2cm bigger in diameter than other props! Then there is the second fastest (it is quite new as I haven't seen that before): http://www.emarineinc.com/products/Torqeedo-1916%252d00-Spare-Propeller-v19%7B47%7Dp4000.html ^This should be faster...

http://www.emarineinc.com/products/Torqeedo-1923%252d00-Spare-Propeller-v30%7B47%7Dp4000.html This one is for high speed! The marking of torqueedo props means: (v = speed in km/h at p = power in watts) Torqeedo suggest to use that prop with light boats, because it can cause the stock...

It seems like watewolf is using torqeedo props. Compare these two prop pics: 1. Is torqeedo original, 2. Is from waterwolf home page: http://cdn-products.austinkayak.com/p_1634_700.jpg http://www.waterwolf.de/products.html The props look exactly the same to me...:D. Maybe the prop was just...

Yeah that was very awesome. The gears looked very small... and what about eddy currents inside that aluminum casing? I'm thinking of something like that in the video, but with clear acrylic cover over the motor and other parts would be form aluminium for better cooling.

If you make waterproof housing for the motor and gearbox under the surfboard then it will silence it. And if you are going 30km/h on water then you wont hear it much anyway :D. You will hear torqueedo because the noise can travel through the leg and transom mount... but if the whole system would...

Another option would be to get inline 5:1 planetary gearbox (like in Torqeedo outboards) for the 80100 motor. And then run at 18s and with the gearbox, the output rpm should be around 1731.6 RPM (18s x 3.7v x 130kv /5 = 1731.6 RPM). BTW Torqeedo has max RPM of 1300. I think with the gearbox...

True, balance is almost perfect. I tried to drill the motor mounting holes very carefully and I think that the motor is centered very well. But there is slight vibration. I think it is from unbalanced prop and gearbox. On water I can only hear motor high pitch noise. It doesn't scare fish when...

I wanted to make the conversion as cheap as possible. First I used turnigy C8085 180kv motor (because it is cheaper than C80100)and Alien's 250a esc. I mounted the motor directly to the mounting plate where the old motor used to be and connected shafts with shaft coupling which I got from ebay...

I got my replacement motor (80100 130kv) mounted on my outboard. Nothing gets hot anymore. And my boat is even faster with the new motor. I forgot my camera at home when I went for fishing and test drive. I hope to get on water next week and get some pictures and video of it

I'm doing the same thing you want to do. Only little bit less powerful. Mine is in the 4hp range. I started of by getting old outboard leg, then buying the electrics for it. I got ''drowned'' 4hp outboard leg from local auction site for 25€. I used turnigy C8085 style motor. I mounted the motor...

Thanks for the plans! Should the blades be curved forward or backwards (in the direction of rotation) for better air flow?

I'll go with the fan. I was thinking of letting somebody in my country to cnc it for me out of aluminum. When the fan spins it makes it self cool and in contact with motor it would cool the motor even more. Would be nice if somebody would share the plans (Solidworks/CAD/etc...) with me. Then the...
