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?
Some guy that supposedly know his stuff said that you will get 1hp out of the pump for every 1kw you put in. I don't know if that is spot on, but may be.
The kawaski 550 have 37hp stock and put out 360lbs of thrust. If we divide the thrust produced by motor hp we get 9.2 lbs of thrust per hp. Maybe you motor can provide peaks of 8hp, so let say max thrust out of the pump will be 73.6 lbs, or 33.4kg of thrust. That's not a lot, but may be enough for a surfboard?

There is already an electric hydrofoil out there..
