Product Description

This is a 2.5HP Seal Kit & Impeller with a 2 1/8" Eye Width and a 3/8" Vane Width and 4 3/8" OD for a Wet End 2.5HP Motor that has about 11.0 Amps at 230V. This Impeller fits between the Face and the Volute of a XP2 Wet End found on some Watkins HotSpring Caldera pumps with Vendor Code 4081. I would advise replacing the Seal when you replace the Impeller.

Note: A 115v motor that uses a 2.5 HP Impeller does not exist a 230V motor would show about 11.0 Amps on High. See chart below for other Horsepowers. Do Not choose a Larger Impeller thinking that it will make your Hot Tub Stronger it will only damage the Motor and make it run hot on high speed. To determine the HP refer to the chart below.. The difference between a 48 or 56 Frame wet end is the spacing of the Motor Thru bolts. The 48 Frame will be 3 5/8" between or 5 3/16" in a X Pattern with a 1/4" Bolt Head and the 56 Frame will be 4 1/8" Between or 5 3/4" in a X Pattern with a 5/16" Bolt Head. 91694150

Note: A 115v motor that uses a 2.5 HP Impeller does not exist a 230V motor would show about 11.0 Amps on High. See chart below for other Horsepowers. 
Do Not choose a Larger Impeller thinking that it will make your Hot Tub Stronger it will only damage the Motor and make it run hot on high speed as well as there are (3) different size wear rings on the impellers so if you choose a different size impeller your wear ring may not work. Measure your wear ring to determine which impeller section you should be in.. 2 1/8", 2 3/8" or 2 5/8" look for the eye sizes in the impeller description area...
 
To determine the HP refer to the chart below.. 
The difference between a 48 or 56 Frame wet end is the spacing of the Motor Thru bolts. 
The 48 Frame will be 3 5/8" between or 5 3/16" in a X Pattern and the 56 Frame will be 4 1/8" Between or 5 3/4" in a X Pattern. 
You must go by the Amperage Sticker on the motor not stickers on the Wet End or Motor especially the BHP Stickers. 
Look on the label of the motor for the two amperages if you have a 2 speed pump or if its a single speed look for a single amperage. An example will look something like this: 10.0/3.5  The 10.0 is the high amperage in this example. 
 
115V Chart Below
3/4HP 8-9 Amps
1HP 11-12 Amps 
1.5HP 16-17 Amps 
2HP 19-20 Amps. 2HP would be very rare
 
230V Chart Below
8.0 = 1 HP
10.0 = 2 HP
12.0 = 3 HP
14.0 = 4 HP
16.0 = 5 HP
 
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 incorrectly that they have 5 HP pumps.
If you do the math two 230V 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.
