Complete Pump, 36745, 36675, 71699, 0974101, Aqua-Flo, 1.65HP, 115v or 230V, 16.0A or 8.0A, 48 frame, 2"x 2", 1 Speed

This complete pump and motor is an Aqua-Flo replacement, 36745, 36675, 71699, 0974101, 115V or 230V, (1) Speed, 16.0Amp or 8.0Amp, 48 frame 2" x 2" XP2 pump and motor...

The 2" inlet and outlet measure about 3" across the threads... Keep in mind if you choose this high amperage pump and have a tub with a wall style 115V plug this pump may draw too much amperage to work with your heater on a wall plug.. Always match the amperage when choosing a replacement 115v pump with the previous motor or you could create some over amperage issues with your hot tub..

BIG NOTE 230V System: If this pump is pump #2 on your hot tub meaning you have 2 big pumps one is the 2 speed and this one is a one speed then there is a better more reliable choice than this choice.. that choice would be here: Complete Pump, Aqua-Flo, 06115734-1,1.5HP, 230v, 48 frame, 2" x 2", 1 or 2 Speed 8.5A, Vendor Code 4081

BIG NOTE 115V System: If this pump is pump #1 on your hot tub meaning you only have 1 big pump and a Circulation pump then there is a better more reliable choice and this.. That choice would be here: Replacement Pump, 39583, Aqua-Flo, Vendor Code 4081, 1.5HP, 115v, 13.0A, 48 frame, 2"x 2", 1 or 2 Speed

NOTE about these Replacement Pumps: Watkins Does Not Make Pumps. They buy different brands of pumps and put their numbers on them.. If you want the original Watkins numbers on your new pump we don't offer that.. What We offer is the exact pump or the closest equivalent to the original pump if it is obsolete that they would buy and put their numbers on from the original pump manufacturers. The main difference between one you would buy from them now and ours is the exhaust vent in the back will not come on our pump.. We think it is a bad idea as it does not allow the motor to cool as it was intended to cool and does not have any redeeming quality for you as an end user.. See the below picture for what will NOT come on our pump.. If you must have that feature Watkins is the only source..  

Note: If your original Pump has this on the back with a hose attached none of my pumps will have that nor will they be able to accept this part from your old pump.. You will save 100's of dollars over the original pump with that attachment that is only used to put heat from the motor under the tub and I believe the motors stay cooler without that device and last longer..

NOTE: The motor on this pump can vary and may or may not look exactly like the one in the pictures but it will be the same specs..

Read this information to Help to determine the Frame and HP.. The way you can determine whether your pump is a 48 or 56 Frame is by measuring the width of the motor. A 48 Frame motor will measure 5 3/4" wide across the back and a 56 Frame will measure about 6 1/2" wide across the back.

For 230 Volt Pumps Look on the label of the motor for the two amperages if you have a 2 speed pump, if its a single speed look for a single amperage. It will look something like this: 10.0/3.5  The 10.0 is the high amperage in this example.

8.0 = 1 HP

10.0 = 2 HP

12.0 = 3 HP

14.0 = 4 HP

16.0 = 5 HP

For 115 Volt Pumps Look on the label of the motor for the two amperages if you have a 2 speed pump, if its a single speed look for a single amperage. It will look something like this: 10.8/2.8  The 10.8 is the high amperage in this example and would equate to a 1 HP.

  8.0 = .5 HP

9.0-10.0 = .75 HP

10.0-13.00 = 1 HP

13.5-15.0 = 1.5 HP

16.0-20.0 = 2 HP

Note: These Amperages are Averages so find the Amperage closest to your pumps Amperage. Note for the Note: 2HP 115V pumps are very rare, do not order one thinking you can add more power. This pump or even a 1.5HP pump will cause your PLug N Play tub to damage the electrical system, Plug, Wires and even the pump motor.

NOTE: Your pump or motor may say a different Horse Power than what you see here, DO NOT go by what is listed on the motor, go by the amperage on the label.

NOTE for the NOTE: TRUST ME ON THIS, everybody lies about their Horse Power. But the amperage does not lie. Most people are told they have 5 HP pumps, if you do the math two 5 HP pumps at 16 amps is 32 amps. Plus a 5.5 KW heater is 21 amps. That means with both pumps running and the heater on it will draw 53 AMPS. I bet your HOT TUB is on a 50 AMP breaker. Therefore contrary to what you have been told you DO NOT have a 5 or 6 or 7 Hp pump.
