That motor does not seem like a good choice for a E-foil. 160 KV is a little on the high side, the prop is probably 7.25" in diameter. Takes a lot of torque to spin that prop. !2 guage wires on the motor are small. The wires come out the wrong end of the motor for typical e-foil application. I would try to run it on 12S to get the best possible performance.
You might want to post the screen shots.
