Product Description

Premium-Efficiency 2-Speed Pool Motor with Integrated Timer

A. O. Smith’s new 2Green two-speed premium efficiency replacement pump motor with integrated timer packs tremendous value into an easy to- nstall package. Energy efficiency continues to drive the needs of the pool market, from legislation to increased awareness of energy costs and environmental impact. And thanks to the 2Green’s energy efficient high and low speed windings paired with an onboard timer interface, energy consumption can be reduced by as much as 58% over single speed motors. The all-in-one integrated motor and timer means less work for an installer and maximum energy savings for pool and spa owners. A. O. Smith’s 2Green is Title 20 compliant** and best of all, there is no additional wiring required for new construction or retrofit installations!

**California’s Title 20 legislation states that pumps > 1HP (total) must be 2-speed or variable speed, and must have a control to default to low-speed (i.e. timer)

I have a Leslie’s hydromax II pump 1.5horse will this motor hook directly to pump. Do I need motor flange also?


A  Answered on 10/21/2020 by InyoPools Product Specialist Hector F.

Hi John, technically yes this motor will mount up to your Hayward Hydromax II pool pump however for us to truly confirm if it is the correct motor replacement we will need the motor model, part, or catalog number.  

?     Asked on 8/6/2017by Brad

I am running my Saltsyslem and Hayward Super Pump {C48L2N134B1; HP 1.5, SF 1.0; 115/230 (CURRENTLY CONFIGURED TO 230) SP-1810-Z1-M} on a T104R timer box in Tennessee. Usually keep the pool open April to late September. It is time to replace the motor. Will this pump essentially be a "plug and play" or will I need to take out my current timer box and/or by some kind of adapter kit? I also plan on getting the GOKIT3SALT tune up kit. Thanks

A  Answered on 8/8/2017 by InyoPools Product Specialist Lennox H.

Hi, Brad. This B977T motor will mount to the Hayward Super Pump housing. You will have to remove the trippers from the T104 timer mechanism in order to power this motor. The chlorine generator will begin producing chlorine once water flow is detected. 

?     Asked on 6/12/2017by Jesse

I have see a lot of discussion about right-sizing your pump relative to pool size and head measurement, but I haven't found anything relative to head when it comes to the low speed setting on a pump. The implication would be that a pump might not being able to circulate in low speed if the head height was too much for the pump. All of the performance charts I have seen imply this. My questions is, does the two speed pump rating account for the ability to circulate at low speed?

A  Answered on 6/16/2017 by Product Owner

I recently bought this motor, my pump is about 12 to 18 inches above the normal waterline. I have no issue with low speed circulation. If I start in low speed after Opening the pump and loosing the prime I need to reprime, I typically do not need to do this on high speed.

?     Asked on 5/8/2017by Tim

Hi again, You just kinda answered a question for me regarding the B977T motor. How is it possible for this motor to have this configuration when it doesn't show on Century's website and is not available through any other source. I'm a pool service tech and would like to purchase but am skeptical. The only 2Green motors available from Century are square flange according to their website and my distribution sources here in Tucson.

A  Answered on 5/9/2017 by InyoPools Product Specialist Patrick P.

Hi Tim, I'm not sure why Century does not have this motor on their website as we have been selling it for years. We currently have 10 of this motor in stock so if you needed to order a few we should not have a hard time fufilling your order.

?     Asked on 5/8/2017by Tim

B977T motor... Century does not show this motor as being produced. Do you take the electronic package and mount it to the standard 2sp motor? If so, what's the warranty status since it's not available from manufacturer?

A  Answered on 5/8/2017 by InyoPools Product Specialist Hector F.

You cannot remove and mount the controls on another motor. This model is still active and on our site and the warranty is 12 months from install/purchase as long as the motor has not been submerged or has shaft seal failure.

?     Asked on 4/14/2017by Rick

I have a heyward super pump 1 hp motor and want to upgrade to a 11/2 hp motor. What parts would I need to change, and what would be the advantage of a 2 speed motor.

A  Answered on 4/14/2017 by InyoPools Product Specialist Lennox H.

Hi, Rick. You will need to change the Impeller - SPX2610C, and get the Tune Up Kit GOKIT3 or GOKT3SALT. The advantage of a dual speed pump is to allow you to circulate your pool water on a low speed to save on energy consumption.

?     Asked on 4/8/2017by Mell

Can I use this motor for my Hayward SP3010EE pump? The current motor we have on it is the ST1152 and we would like to upgrade to a dual speed that has the timer already installed.

A  Answered on 4/10/2017 by InyoPools Product Specialist Lennox H.

Hi, Mell. Yes, this B2977T motor along with the Super II Pump Tune Up Kit GOKIT2 or GOKIT2SALT can be used to convert your single speed pump into a dual speed pump.

?     Asked on 3/26/2017by Greg

Hi, Looking for a two speed replacement motor for a Hayward Super Pump model C48L2N134B1 SP-1610-Z1-M 1 1/2 HP motor, would this work? . Also can the display for the timer be turned 180 degrees? Thank you, Greg

A  Answered on 3/28/2017 by InyoPools Product Specialist Scott W.

You could go with that two speed motor or spend $7 more and get a variable speed motor, ECM16CU, for your Super Pump which is going to be more energy efficient than the two speed. Make sure you get the GOKIT3 for your motor install as well.

I need to replace my Pentair # 168453 1.5hp HP 1.65 will this motor be compatable?

A  Answered on 2/13/2017 by InyoPools Product Specialist Lennox H.

Hi, Kelly. The 1 HP Full Rate Dual Speed w/ Digital Controller - B2982T is the correct dual speed motor with controller that will replace p/n 168453.

?     Asked on 1/29/2017by Samira K

For an AO Smith motor (Model B230SE) that is 2HP and Y56J Flange, is there a kit that I need to get to mate this motor up to my existing pump basket/strainer housing?

A  Answered on 1/30/2017 by InyoPools Product Specialist Scott W.

I would need to know the model of the pump that that motor attaches to. If you do not know the model please attach a side view picture of your complete pump and I can help you with that.

?     Asked on 1/22/2017by Inyo Visitor

I have an old AO Smith motor (Model B230SE) that is 2HP and Y56J Flange. I noticed this is a 1.95HP motor if you consider the service factor of 1.3 and the rated HP or 1.5. Is there any issue with using this motor in place of my current single speed motor?

A  Answered on 1/24/2017 by InyoPools Product Specialist Hector F.

There would not be an issue in using that dual speed motor due to the fact that the total hp is near exact to your original motor.

?     Asked on 1/14/2017by Linda

I am replacing a pool motor (of indeterminate mfg). Current specs show; Volts: 115/230, HP:1.5, AMPS: 17.2/8.6, SF: 1.00, INSUL CLASS: B, AMB: 50 Celcius, TIME RATING: CONT. Will this be a good replacement ?

A  Answered on 1/16/2017 by InyoPools Product Specialist Lennox H.

Hi, Linda. You will need either the B2975T (FR - 56J) or the B2982T (FR - 56Y) depending on the frame style of the motor you have.

?     Asked on 12/26/2016by Jichao

Will this motor replace my Hayward single speed motor C48L2N134B3 1.5HP 115/230 Volts SF1.0 PH1?

A  Answered on 12/27/2016 by InyoPools Product Specialist Adam Y.

Good morning Jichao, Yes this would be a good replacement. Same flange and frame size. Remember to replace the shaft seal and o-rings when you swap motors.

?     Asked on 11/25/2016by Gem

Will the B977T or B2977T serve as a direct replacement for the motor on my Hayward SP2600 VSP pump? I'm having a hard time finding the replacement part number for the SP2600 VSP motor.

A  Answered on 11/28/2016 by InyoPools Product Specialist Andy O.

Hello Gem- The B977T/B2977T is only a dual speed motor. The direct replacement for your SP2600VSP would be the 1.65 HP Variable Speed Pool Pump Motor Round Flange - ECM16CU.

?     Asked on 10/4/2016by Loyde

I have been using & replacing the AOSmith STS1152R 2spd motor for years; the bearings go bad after about 6mths & I have the motor rebuilt locally and get another 18mtns out of it till the windings go. Any reason to believe the bearings/windings will last longer on the B977T? When it is time to replace the B977T can I buy just the motor and transfer the digital timer from the old one?

A  Answered on 10/4/2016 by InyoPools Product Specialist Scott W.

It might be a little tricky with the B977 having the capacitor on the top of the motor. Otherwise, to answer your question, if you have a generic digital timer that you bought separately from the STS1152R I don't see any reason why it wouldn't work with the B977 if you're able to find a way to mount it.

Hello, I have an A.O. Smith Model# K48N2N106C1 2hp. Is this motor a good replacement? Thank you!

A  Answered on 8/17/2016 by InyoPools Product Specialist Scott W.

Yes, that would be a great replacement if you're looking for a dual speed motor. That will fit, but won't give you the same amount of horsepower as your current motor. The total horsepower on your current motor is 2.6 and that dual speed motor is 1.95. Unfortunately, we don't have the dual speed with a timer that matches your current total horsepower, but we do have a dual speed w/out the timer. The part number is 5389X.

?     Asked on 6/4/2016by LIsa

I have a Hayward Swimpro Voyager 2-speed pump that I think is 2HP. The part number on the motor (SP1520Z24ESC) does not match any of the motors listed in the owner's manual. My pool is 26'x15' oval, 4.5' deep, approximately 10,500 gal. Do I really need a 2HP motor, or can I use a less powerful one? Can I just replace with another Hayward motor since the owner's manual shows all the same pump parts used with several different HP'd pumps?

A  Answered on 6/5/2016 by InyoPools Product Specialist Patrick P.

Hi Lisa, If your motor is 230V then you will require the BN51 2 HP Dual Speed Motor here.

?     Asked on 5/25/2016by rob

I just received my new motor B2977T. the impeller set screw from my old motor does not fit the new motor. Where can i find a proper fitting screw?

A  Answered on 5/26/2016 by InyoPools Product Specialist Lennox H.

Hi Rob, The impeller screw is no longer needed so you ca do without it.

I have a Emerson EB 228 1.0 HP motor (Frame 56 J). I believe it has a round flange. It is end of life. Can I replace it with this motor? Thanks!

A  Answered on 5/5/2016 by InyoPools Product Specialist Alan M.

Hello, I would recommend you replace your EB228 1HP motor with B975T 1 HP Full Rate Two Speed Motor W/ Timer. I would not recommend increasing the horsepower without identifying your PUMP style and determine if you need to change the impeller.

?     Asked on 5/2/2016by Rob

Is this 2 speed motor a proper replacement for motor part# 7-193633-24 off of a Jandy PHP1.5 pump?

A  Answered on 5/3/2016 by InyoPools Product Specialist Hector F.

Yes this would be a suitable dual speed replacement motor for your current model.

I have a Hayward SP1610-Z-2M, HP 1.5/.25, A 8.0/2.5, RPM 3450/1725, frame X56J. I need the motor, Thanks

A  Answered on 9/8/2015 by InyoPools Product Specialist Lennox H.

Hi Robert, The 1.5 HP 2 Spd 230v 56J Motor (STS1152R) would be the correct replacement motor which would be wired to your dual speed timer. The 1.5 HP Full Rate Two Speed Motor W/ Timer - Round Flange (B977T, B2977T) would also work but it has a built-in timer so you would not have to wire the motor to an external timer.

?     Asked on 8/17/2015by Taz

Hi there I have a Hayward pump model C48L2N134B1. I would like to replace that with this one. Will this be a direct fit to the motor plate? I have those square looking strainer basket. Thanks

A  Answered on 8/17/2015 by InyoPools Product Specialist Hector F.

No this 2 speed motor is actually stronger than than the motor that you currently have. If you want to use a 2 speed model then you would need model B975T.

I have a Hayward SP2610X15 pump and need to replace the motor. Will this motor work as a replacement?

A  Answered on 6/17/2015 by InyoPools Product Specialist Joe S.

Yes, the B977T will fit right with that pump do not forget a GOKIT3

?     Asked on 4/24/2013by Guest

Can the timer on the motor be removed to mount on a wall?

A  Answered on 4/24/2013 by InyoPools Product Specialist Patrick P.

Unfortunately the timer control on the motor is permanently attached to the motor and can not be removed.
