Spa jets are not at full output. I have a new

Normally I would tell you to check your warranty (but seems you don't have manual)
* Check panels and equipment for contact number and call for support.

*** Following is for information only.***
* Sounds like a restriction in output of pump system.
* Do not allow a "Humming" pump to continue operation. Burn out may occur. Turn off power.
* Need to check the water flow. Start from suction intake.
* Check screen and clean.
* Check intake hose(s) for obstructions or restrictions.
* Is there sharp bends or weakness in hose. It should be a ridged pipe with no sagging or squishy parts. (It will collapse during high suction.)
* Check the intake manifold and shutoff valves for operation. (all intake valves should be fully open when in use.)
* Keep following water pipe (flow) to filter basket(s) then pump. Check and clean.
* Output may have a manifold valve system. Check and clear. Confirm the output is directed back to pool.
* Suggest contacting your local pool service for additional advice.
* The following has more detail in pool operation. (may void warranty.)

Aloha, ukeboy57

check to see if pump lid seal is ok and check to see if intake unions are tight make sure water is in the pump basket

make sure basket is full and check the incomming union make sure tight also make sure top seal is ok

it sounds to me that your electrical contacts are not tight or the motors windings are overheating so seak the help of an electrician and ask him to test the start and run amperes of the system if thats fine then i think your pump seals are faulty

your pump should be just fine once the water starts flowing again. You may have run it too long without enough water to cool the seal.
If it is leaking water between the Jacuzzi Pump housing and the motor then you will need a new pump seal. Those are common pool parts.

Sounds like there is an impeller problem. A 1hp emerson should be fine. Take it apart and recheck impeller and diffuser. I am assuming they gave you a new seal to replace with the motor.

a suction leak will cause the pump not to prime... check the lid gasket, lid for cracks,pipes and valves. you can rap the fittings with electrical tape, to help you locate leaks.. a shaft seal is a good start, this will allow you to ree the condition of the impeller . it may be plugged, also see if there is cracks in the hair basket it will allow trash to get into the impeller

Have you opened up the wet end? If you have pine trees near you, it is probably a blocked impeller and needs to be cleaned. If this is not the case, is the pump basket full of water or air?
If it is full of water, it is either the impeller, or the motor bearing.

if it is full of air, it is an o-ring or shaft seal. more likely the shaft seal. Always check the impeller first.

That sounds like the pump is cycling. Is there air in the pump basket or is it full of water? If there is air in the basket, you have a leak somewhere. Could be the lid has a crack, or the o-ring, under the lid has gone bad.

The pump motor may be going out on you also. If it is hot to the touch, there is a safety feature in the pump that will shut it off before it becomes too hot.
