I now know now I have the wrong motor for my boat 7.5 lb, hydro, have a 3660/2726 KV, 3s parallel, is there any prop I could run with out a new motor? and more $$$, for new motor, I do not care how fast I go. I put on a new water cooling jacket on motor, as wires burned a little with a 42X55 prop. motor and ESC still working. Thank You
