We offer spa motors in many form-factors and horsepower configurations from AO Smith. All of our motors are NEW, not reconditioned. These became an industry standard in 2006-07 (because most other brands DO NOT SELL SERVICE PARTS!). Buy with confidence knowing that you are getting a high-quality motor that is FULL of copper that will last you for years.
If you are looking to replace both the "dry" and "wet" ends of your motor, check out our pump and motor combos.
How to Determine Your Spa Motor Size
The easiest way to determine whether your spa takes a 48-frame or 56-frame motor is to measure between the thru-bolts.
These are the bolts that run the length of the motor and screw into the four legs of the wet-end volute or seal plate.
3 5/8" between bolts = 48 frame motor
4 1/8" between bolts = 56 frame motor
