Magnetek/Century M5238 Two Speed, 56Y Frame Thru-Bolt Motor Description

These quality Magnetek Century 56 Frame Thru-Bolt Motors are found on many different models of spa and pool pumps. Some of these pump brands are Aqua-flo, Vico, Waterway and others.

These motors directly replace the "original" motor that came with your pool pump. No pump manufacturer manufactures their own motors. We sell Magnetek Century motors because we have found them to be long lasting and reliable. Century Electric Motor is now part of A.O. Smith.

Important Note - These motors have a 4-1/8" distance between the thru bolts. Not to be confused with the more common 48 frame motors with a 3-1/2" spread between the thru-bolts.
