Would 2 of these be able to pull a surfboard with 15kg on it?

I know this is wired but do you think this will pull a boat on the water it's about 3 to 4 pounds and it's a hydro plane will it pull it

I usd the turnigy 600 series 1220kv brushless outrunner motor and a 100A ESC with this unit and got abt 6lbs in thrust. Then I switched to the S3674-1660 1660KV with a 60A ESC and got about 9lbs of thrust. Unfortunately the esc caught on fire.

just received edf. It was my first, read the reviews and thought ok, it may needs balancing but let's try it at low voltage... 10V was the setup with a 100A sentilon ESC-1200kv motor, on a bench. It was badly unbalanced! I tried it a few times but all of the sudden 2 of the blades flew away!!!??? and the thing started vibrating like crazy. Going to return product for a replacement. Shaft seems to be a problem too. Without the fan, this thing vibrates badly!!!

Hallo. Leucht leider bei mir unrund. Benutze eine KB45-12L 1400kv Brushless Inrunner. Der Fan k├Ânnte besser entgrattet sein. Vielleicht eine schlechten erwischt. Aber sonst ist Hobbyking super. Gruss aus Deutschland

I'm tested this Fan unit using a KB45-17XL 700kv Brushless Inrunner, TURNIGY Sentilon100A HV ESC on 10 cells and I'm getting 2,300 watts at 70Amps. Need a bit of balancing using epoxy resin.

Exellent edf! light and produces enough thrust plus plenty to spare!!
although the correct motor/speed controler combination is vital to get the most out of it!
