1) Under heavy loads, usually in Sport mode, Motor disconnects from Propeller. I realize this is a heavy vessel at 220 lbs + 99 ib Battery, rated for 15 hp, I
2) Propeller Cavitates at speed, when planing it is constant, are there any other propeller options? Check out the winner of this 3D printed prop test;
