I am pretty sure that my US Motors, EST1072 is bad. In reading all of your great materials, I have determined that the Century UST1152, 1.5 HP motor is the best bet. Can you confirm and also let me know what else I need for a Hayward Super Pump (SP-1600)? Thanks.
I am showing the correct motor is the ST1072 for a EST1072.
However this is not the normal pump motor for the Hayward Super Pump 1.5HP. The UST1152 is the correct match for your Super Pumps (SP1600).
I would also recommend getting a tune-up kit for the Super Pump. Here is a link to that kit…
