Hello Rich, From the model number you provided, it shows you have a Hayward Super 2 Pump. According to the Hayward Super 2 Parts List, you can replace your 2HP single speed motor with the A.O. Smith 2 H.P Round Flange Dual Speed Full Rate Motor (B979). If your HP on the motor is different, you can reference the parts list for the applicable equivalent dual speed motor. I would also strongly recommend replacing the seals and gaskets (Tune Up Kit Hayward Super II) when changing out the motor. Please click on the provided links for current pricing information. Have a great day!!
