I have a GE Model 5KC39PN2822BX that just died on me. Your replacement pump the "Marathon Round Flange Motor" shows no longer available. Do you have something that will work for me?

I've a Marathon Electric 1 HP Motor C1318 installed in a 10,000-gallon pool with Hayward C-750 filter. The filter needs replacing due to corrosion and rust. I may replace the C-750 with a C-500, except if I understand correctly I should reduce the motor to 3/4 HP, right? What are advantages/disadvantages of reducing the HP? What parts would I need? Better to replace the filter with a C-750? I'm concerned that the same corrosion and rust may have also affected the pump but it seems to run OK

A     Answered on 6/7/2015 by InyoPools Product Specialist Patrick P.

Hi Ed, If you reduced your filter down to a C-500 you would need to reduce the HP of your pump so the small filter could handle the output of your pump. The advantages to reducing your HP is that your cost of operation will be less as the 3/4 HP pump costs less to operate than a 1 HP pump. The disadvantage of reducing the HP is that you will need to also replace your impeller to 3/4 HP so there would be this additional expense. I would suggest replacing your filter with a Hayward C7512 Star Clear Plus Filter and reducing your pump motor to 3/4 HP.

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?

A     Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

I'm looking to replace my G.E motor. My model is a C1318. Your description matches but you say this is a Marathon motor. Is this right?

A     Answered on 1/18/2012 by InyoPools Product Specialist Patrick P.

G.E. and Marathon are one in the same. G.E was purchased by Regal Beloit and is now under the Marathon name. The quality of the motor has not changed.
