According to Regal Beloit ( the company that owns Century ) the USN1202 is 6.42” diameter. My guess is they’re the same diameter.

Other than cost, the dual speed and variable speed motors are better.
Thanks, yes I think it would fit too. But, as everyone is recommending, I am sold on the benefits of a Variable Speed Motor and decided to go for it.

Was all set to order the Pureline 1.65 HP model # PL2605, but after a bit more research, decided to buy just the motor from that model:
The Century V-Green 1.65 HP Variable Speed Motor (Model ECM16CU), comes with 18 month warranty and saves me a few couple of Benjamins.
A.O. Smith V-Green 1.65 HP Round Flange 56J Variable Speed Motor - ECM16CU - INYOPools.com

And the motor it is a easy swap on my Hayward Super II pump, so I don't have to worry about cutting the pipes and stuff.
They have a detailed install video for it on You tube: How To: Install A VGreen 165 Variable Speed Pool Pump Motor

Haven't ordered it, want to talk to Inyo Pools once to make sure I didn't miss anything before ordering it.

Meanwhile my pool it getting dirty, had a rainstorm and all the debris is in the pool :cry:

For that motor, you will need the following:

SPX3000BN.....Diffuser
SPX3005R........Wear ring
SPX3010C........Impeller
SPX1600R........Diffuser gasket
SPX3000T........Housing gasket
SPX1600Z2......Seal.

If you go with the 2.7 hp motor, you won't have to replace the impeller or diffuser.

Based on the age of the pump, I would probably go with a new pump.

Oh man..... and here I thought I got it all figured out. I wanted to avoid cutting the pipes and re-plumbing. Also, trying to keep the cost low as possible.
I will consider moving up to the 2.7 HP version (Model ECM27CU).

Would you mind giving your opinion on the the following motor & pump?
U.S. Motors AVSJ3 EcoTech EZ Variable Speed 3HP Pool Motor
Harris 72525 Variable Speed Pool Pump, 3 HP

You can use the smaller motor, you just have to replace the impeller, diffuser and wear ring. No need to cut the pipes.

Well, according to these specs from InyoPools, my pump (SP-3015X20) already has the SPX3000BN Diffuser and the SPX3005R Wear-Ring.
Only the Impeller is different, the pump has SPX3015C and you are recommeding the smaller SPX3010C.
So, looks like I need to change only the impeller, get a new seal kit and be all set with the 1.65 hp VS pump.

I am also liking the U.S. Motors AVSJ3 EcoTech EZ Variable Speed 3HP Pool Motor for a few extra $$.
