Hello
I am looking for the pool pump moter replacement. Currently I have Whisperflo WFE-4 pump case and a.o.smith 7-177450-03 1hp motor. This motor is making a loun noise while running. I’d like to know if you have a replacement motor and also if I can upgrade to 1.5 or 2 hp motor as well. Don J
The drop-in replacement motor for the Whisperflo WFE-4 is model B2841.Click Here to View the B2841 motor
The more energy-efficient option is a variable speed motor. The variable-speed motor would be model ECM16SQU.Click Here to View the ECM16SQU Motor
Unless you need more flow for a water feature or spa jets, I would stick with the current 1HP option. The larger HP will cost more to operate and put more strain on the filter. However, you could go with a larger HP if you change the pump impeller as well.
