I am looking to replace my spa motor. When I entered the current one Century LASAR Spa Motor 7-184821-04 I was taken to this motor. This is the correct replacement before I order. Thanks for your time! Clint

Hi, Clint. The BN62 is the correct replacement motor based on the info provided. I will need to know the model of the Wetend in order to locate a pump what will match. This is normally found on the black plastic where the pipes are going in and out of the pump. If you can find any part #'s stamped into the plastic that would be helpful. Also if you could let us know the plumbing size going in and out of the pump normally this will be marked on the plumbing itself and would be something like 1.5", 2" or 2.5".

Patrick, Thank you for your quick response. I have attached some more photos as I was able to get the entire assembly out. All my plumbing is marked 2'' I believe. The only stamped number I found on the Wetend is 91231605. Hopefully this additional information will help you. Thanks Clint

    Thanks Clint those photos really helped as well as the part # you found on the wetend. The part # you found on the wetend belongs to this Aqua Flo XP2 Pump and based on your BN62 Motor you will require this specific pump here 3 HP 2 Speed Aqua Flo Spa Pump with 2" Ports We do have this pump in stock ready to ship!

Hi I am replacing a Balboa water group 1015109 part , volts 230 , hertz 60, amps 8.8 / 3.4 , epp 4.5 speed 2 ul model puup220258220

What you actually have is a 2 hp Vico Ultima that was labeled as a 4, 4.5 or 5 hp pump, we also show it as discontinued. The Waterway you reference will not line up union to union & will require some slight plumbing modifications & is also to big of a HP to use. We can match the original but it will be under 2 part #'s, 1 for the wet end portion & 1 for the motor. We can however assemble prior to shipping. See/use part #'s 1215132 (34-430-1176) & BN-51 ( 35-126-1120W ). If you could just let us know when you place the order so we make sure to process the order properly.

Hello, I'm replacing a A.O.Smith Spa Motor Cat BN62 Part 184821, I'm having trouble finding the specs online and want to know if the measurements are the same or will I have to do some conversions or replace additional parts. Thanks in advance.

Hi, Jeremiah. The BN62 is the correct replacement motor based on the info provided. I will need to know the model of the Wetend in order to locate a pump what will match. If you do not have that info, pictures will due.

We have a Legacy Whirlpool Spa. We are trying to determine if this is the right replacement motor. Our specs are as follows: AO Smith Motor; Serial Number #PF-1108040399; Model Number #PF-2MCF; Part No. #3421021-0a8qmr; 230 Volt, 3450/725 RPM; 9 - 2.8 Amp; This is a Executive 48 by Waterway. Can the plug on the end of the pump be removed to install a insert fitting for a vacuum hose?

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

Hi, Dave. The AquaFlo Gecko Alliance XP2 Pump - 06120500-2040 is what we have that can be used as a replacement. I would not recommend because it does not have a strainer assembly.

My spa pump motor froze up, Model # to the spa is 3070 B3 A01. Is this acceptable replacement, Thanks

A  Answered on 5/11/2017 by InyoPools Product Specialist Lennox H.

Hi, Keith. In order to locate the correct replacement pump, I will need the pump model # or specs. I'm unable to cross reference pump based on the spa model.

I am in need of a new pump and motor for my hot tub and was wondering if this is a suitable replacement. My current model number that I now have is A century laser #7-184821-04 and the pump is a Horizon spa and pool # 34-270-1525 any info and help you could give me would be helpful.

A  Answered on 7/15/2016 by InyoPools Product Specialist Alan M.

According to the motor information, you have a 3HP/2SP motor. A suitable replacement pump that matches your motor speed would be the Waterway Executive 48 Pump - 3 HP, 230V, 2 Spd. - 34212211A. Please verify that your intake and discharge ports are 2" before placing the order.

Does this pump come with a cord?

A  Answered on 10/30/2012 by InyoPools Product Specialist Patrick P.

Per Waterway,  the 34218211A Executive 48 pump does not include a cord.  Most people reuse their existing cord.  There are two special order 4 ft cords for this pump, one has a J&J Mini plug (741-CGGG-45P) and the other has a 4-pin AMP plug (741-CGGG-45X).  Waterway does not have one with just exposed wires.  Please feel free to call us to check price and availability of these cords.
