Currently have a SP2605X7 (motor is a 3/4 HP c48j2n131b1 by AO Smith) that I’m interested in replacing with either a 2-speed model (manual control/switch) or possibly a reasoably priced variable-speed motor. The B977T or ECM16CU looks particularly intriquing. I believe I would also need a new impeller (spx2610c or spx2615c I think?). What other motors should I be considering or parts might I need?
Hello Justin - The only other option I can think of is the standard 2-speed motor without the built-in control. The model is B2977. The B2977 does not come with a switch. You could add a switch or connect the motor to a 2-speed timer.
