Electric Motors for Hot Tubs
48 Frame, 56 Frame, C-Face & 56J Frame

Hot Tub MotorsAttached to the spa pump (which circulates the water in your hot tub) is an electric motor which powers the pump. If you have questions about which motor your spa needs, just email us at info(at)cnytubs.com and we can answer your questions.

Unless your current pump was under-powered (ie. wimpy water force coming out of the jets), we recommend you replace your spa pump with the same or similar horsepower as your existing pump. In general spa motors should have 1 HP for every 4 to 6 standard size jets . Overpowering your hot tub with too much horsepower could damage your jets or plumbing, so it is important to get the right sized motor for your spa.

How to Determine Your Spa Motor Size (48 frame or 56 frame)
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.

Measure the distance between the "Thru Bolts" on the motor that attach to the wet end/pump:

3-5/8" = 48 frame motors
4-1/8" = 56 frame motors


Other style motors such as square flange and round face ("C" bracket) are all 56 frame motors.
