I bought a house recently, and one of the pool pumps (for the negative edge) started grinding and has now died, its out of warranty. I've been browsing the forums and have seen that a good replacement motor is the Neptune brand, and they are waaay less money for just the motor. Most companies are asking for like 2500- for an install of a new hayward which I can do myself if it comes to it. Can anyone direct me to the proper Neptune replacement motor for this pump (and any parts I might need to swap)? I'm also wondering if it can be tied into my controller which is an omnilogic, or if I will have to program it on the motor itself and just keep it separate. Not the most pool savvy, yet. Pics attached, its the rightmost pump in this pic.

ty in advance!

The Nidec Neptune NPTQ225 is the correct motor. The OEM Go Kit is SPXHKIT100 (shaft seal, gasket, O rings).
The motor will have to be controlled through a relay. Using the relay now used for the waterfall, a speed can be set on the motor and will operate at that speed when the relay is actuated. The wiring for that is in the manual
