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)

Is this two speed motor a good replacement for the existing .75hp motor on my Jandy Stealth JHP pump. The current motor that came with it is an A.O. Smith Centurt Centurion part number 7-193631-24. The Frame number is S56J. I have 115 voltage currently. Thanks Colin

A  Answered on 6/16/2019 by InyoPools Product Specialist Lennox H.

Hi, Colin. Yes, you can use this B2973T motor as a replacement based on the info provided.

Will this work with my current 1hp Hayward super pump?

A  Answered on 5/29/2018 by InyoPools Product Specialist Hector F.

If you are currently using the original Hayward Super Pump motor that came with the unit then yes this motor would be a suitable replacement.

Will this motor work as a replacement of my super pump C48J2N131B1? If not, is there a dual speed motor that will? Thanks!!

A  Answered on 5/8/2018 by InyoPools Product Specialist Lennox H.

Hi, Jeremy. Yes, it will if you're using 115 volts to power your current motor. 

?     Asked on 4/27/2018 by Robb

I am considering switching to SWG, but I do not have a stand alone timer. Is it possible/easy to connect a SWG to a pump/timer combo similar to B973T? Or are there SWG that have auto flow control, or a built in timer? Thanks, Robb

A  Answered on 4/28/2018 by InyoPools Product Specialist Lennox H.

Hi, Robb. You cannot operate an SWG using the Timer on this motor. However, you can wire this motor directly to the breaker and install a timer to operate the SWG.

I have a Leslie Hydromax pump, spx3010c 1hp impeller, and a Century 1 Hp. Centurion switchless Motor B128 with a 115 volt feed to the pool. Could I use this motor if I got a 3/4 hp impeller?

A  Answered on 4/2/2018 by InyoPools Product Specialist Lennox H.

Hi. Yes, you can use this motor if you use the Impeller - SPX3007C

?     Asked on 1/8/2018 by

Is it possible to remove the timer at a later date and run the extra high voltage line to have my Hayward AquaPlus manage the speeds? Will the pump need any accessories to do this? Will it void the warranty?

A  Answered on 1/9/2018 by InyoPools Product Specialist Lennox H.

Hi. You're not able to bypass or remove the controller of this motor. Making any changes to the motor or the controller will void the warranty. 

?     Asked on 1/7/2018 by

Can I use this to replace the motor in my SP2607X10 (1 HP - Service factor 1.1)? I will also have to buy the Sp2607-c impeller, correct?

A  Answered on 1/8/2018 by InyoPools Product Specialist Lennox H.

Hi. Yes, you can use this 2-Green Motor - B973T with model SP2607X10 using the same impeller and using 115 volts. The SP2607C is the correct impeller for your model pump using this motor. I will also recommend that you get the Hayward Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT

?     Asked on 8/2/2017 by Fil

Is this a suitable replacement for my Hayward SP2607X10 with a UST1102 motor (C48K2N143C1C)? I need to replace my motor and would like to upgrade to something more efficient and quieter. I only have 115V. Thanks.

A  Answered on 8/3/2017 by InyoPools Product Specialist Lennox H.

Hi, Fil. Yes, this Century B973T Motor is compatible with the SP2607X10 operating at 115 volts. I would also recommend getting the Hayward Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT

?     Asked on 7/10/2017 by Joel

I have a Hayward Superpump SP2610x15. The motor on the unit right now is 1 Hp with SF of 1.1 and it's wired as 110V. Would this motor act as a replacement as 1.5hp is too much pump for my DE filter.

A  Answered on 7/12/2017 by InyoPools Product Specialist Lennox H.

Hi, Joel. It appears that the motor was downsized to a 1HP uprate pump if the current motor is rated at 1hp with an SF of 1.1. In this case you can use this Century B2973T 2-Green Motor. I would also recommend double checking the impeller # before purchasing and if on low speed this motor will provide adequate water flow. 

?     Asked on 6/27/2017 by Phil Beukema

How do I replace the battery (that stores the settings)?

A  Answered on 7/4/2017 by InyoPools Product Specialist Lennox H.

Hi, Phil. Unfortunately, that's not sold as a separate part. 

?     Asked on 5/30/2017 by

Will this motor replace C48K2N143C1C mated to a post 1984 Haward Max Flo pump? Will I need a new impeller? I am also worried about having to modify the pump cradle after reading previous reviews.

A  Answered on 5/31/2017 by InyoPools Product Specialist Hector F.

Yes, this dual speed motor is a compatible replacement. Just keep in mind that this one only works with 110 volts. You can use the same impeller and the motor will the same thickness.

?     Asked on 5/28/2017 by allan

the model number on the pump head is long gone do i have to pull the impeller for the number. {I'd like to keep my panels going during this cold California spring]

A  Answered on 5/29/2017 by InyoPools Product Specialist Hector F.

You should not need to pull the impeller to find a part number on it in order to identify the pump model. It should be molded into the impeller face. If you cannot locate a pump model then you can send in a few images of the front pump housing through our support request page so we can try and identify it.

i have a ao smith hayward super pump II

A  Answered on 5/25/2017 by InyoPools Product Specialist Lennox H.

Hi, Allan. The motor is compatible with the Hayward Supper II Pump, I will need to know the impeller p/n to confirm the correct size motor.

?     Asked on 5/24/2017 by allan

I have a oe smith 3/4 hp k48k2n104 will this motor work as a replacement? Also which shaft seal kit should i use

A  Answered on 5/24/2017 by InyoPools Product Specialist Hector F.

This can be used as a dual speed replacement as long as the control box does not interfere with the pump housing design. Also, keep in mind these need to be wired at 110 volts.

?     Asked on 5/16/2017 by Laura

On the previous question it was stated that this motor would not be adequate at greater than 15 feet of head. My pool is 18 x 36 approximately 29000 gallons, I have 1 1/2" piping and the flow rate is 60 GPM.I have only 1 skimmer located at the deep end about 36 feet away from pump. I have 4 inlet lines running off the same line about 25 feet from pump. I do not have any additional accessories like water falls, heaters, etc. Can you tell me the feet of head?

A  Answered on 5/29/2017 by InyoPools Product Specialist Lennox H.

Hi, Laura. Your feet of head is about 45 on the suction side.  We will also need to know the model of the pump housing that this motor will be operating to find out if this motor will provide adequate water flow on low speed.

?     Asked on 5/12/2017 by

I really wanted to switch to a variable speed pump but I only have 115V connection. Changing to 230V is not an option at this time. Will this pump fit my Haywood SP2602X10? The current motor on this is an AO smith's C48K2N143C1C. HP=1 SF=1.1.

A  Answered on 5/12/2017 by InyoPools Product Specialist Lennox H.

Hi. Yes, the B2973T motor can be used as a replacement. Operating the motor at low speed will is only adequate with a Feet of Head at 15. The Hayward Super Pump Tune Up Kit GOKIT3 or GOKIT3SALT is recommended when replacing the motor.

?     Asked on 4/16/2017 by Sean

I'm just checking to make sure this motor will fit a Hayward Super Pump model # C48J2N131C1C and if you can offer any discounts? Thank you, Sean Ptak Snowroost1@yahoo.com

A  Answered on 4/16/2017 by InyoPools Product Specialist Scott W.

Yes, that motor will fit your Super Pump but you will need to upgrade your impeller if you go with that motor, part number 5110-10CA.

?     Asked on 3/28/2017 by Gokhan

I currently have a Hayward Super Pump (SP2610X15) with an AO Smith 1.5 HP Motor (C48L2N134B1) and am looking for a variable speed replacement. Would this pump do the trick?

A  Answered on 3/29/2017 by InyoPools Product Specialist Lennox H.

Hi, Gokhan. The B973T motor is not a variable speed motor, it's a dual speed. The ECM16CU along with the Hayward Super Pump Tune Up Kit GOKIT3 or GOKIT3SALT would do the trick.

?     Asked on 9/6/2016 by NADINE

Would this motor replace the HAYWARD A O SMITH MODEL #C48K2N143B1? I have a rotary timer - would I have to take this out in order to install this motor with digital timer? Is there any additional part I ought to get along with this?

A  Answered on 9/13/2016 by InyoPools Product Specialist Lennox H.

Hi Nadine, This B973T motor can be used as a replacement for the C48K2N143B1 motor if you have 115 volts. If the motor is the only item being powered by the timer you can remove the trippers and wire the motor to the timer just for power. I would recommend replacing the pump seal and o-rings but we will need to know the model of the pump in order to locate the correct seals.

?     Asked on 8/15/2016 by carlos m morales

Cab it be used as replacement motor for a hayward pump.

A  Answered on 8/20/2016 by InyoPools Product Specialist Lennox H.

Hi Carlos, This motor can be used on Hayward pumps. If you can provide the pump model and or motor mod I can confirm if this motor will be the correct replacement.

?     Asked on 7/21/2016 by ice

Does it work on Above ground pool (without damaging the pool liner) And does it come with a normal 115v outlet plug so we can plug it to a GFI outlet ?) we don't use outdoor breaker box.. we only have a 115V GFI outdoor outlet. Lastly will it fit Jaccuzi 2 speeds 1hp pump ?

A  Answered on 7/21/2016 by InyoPools Product Specialist Scott W.

It doesn't come with the cord but it would fit your jacuzzi above ground pump.

?     Asked on 5/6/2015 by patrick

Will this motor fit my hayward super pump 3/4 hp?

A  Answered on 5/6/2015 by InyoPools Product Specialist Patrick P.

Yes this motor will fit a Hayward 3/4 HP Super Pump but can only be wired 115V, so if you need to wire 230V then at this time there is not a digital speed motor available.
