Hi there. No, i only used 2 motors with 1.5 hp each motor , so it is 3hp now but only 2 motors. I have 2 spare 1.5 hp motors, that is why i utilize it so that they will not be junked, and buying a new motor that is 3 hp can cost higher. I connected it to the other motor so it will help the other motor thus their power would be equal to 3hp. Thank you 💚
