I have a Hayward SuperPump SP2610X15 with a Century C48L2N134B1 - 1.5 HP/230V Motor which needs to be replaced. Is the UST1152 the direct replacement? What is the seal kit #? I also woudl like to know if the Variable speed V-Green 1.65HP ECM16CU could be used as an option. What are the benefits, how do you program it, and would that replace my pool timer? Trying to justify premium. Thanks
