Other than power, do you have other issues?
You may have pump bearings starting to seize for example. Any vibrations, wear ring worn on one side and not the other?

OK the hole idea
Changed the hole pump brand new sbt pump with impeller Solas concord 11/19 carbón ring is old getting a little water in
The pwc is a 2005 wake not the supercharged one
the only thing i see is no much power there could be a little vibration on the engine but i think it is the normal thing

Your pinch washer may be pinched causing drag when you replaced the pump. And, did new bearings go in at that time?
Normally, i would recommend a compression test, but in your case, I would do a compression test, then remove the pump and then do the compression test again. This will tell us if you have a pump issue and or engine issue.

ok can you please tell me what is the pinch washer????
i have done a compression test and i got 130-140 on 3 cilinders i have the pump off now will do the compression test without the pump later today and let you know
The pump was all new berings shaft impeller housing all of it
Well,,, I know there is a pinch washer on the 2-strokes. Not sure about the 4-tec engines.
I'll have to look at a manual when I get a chance..
I'd still do the compression test as this will help with what direction to head. I believe oil can come out the PTO if the shaft is removed. And, you want the shaft removed to get an accurate test (no drag from the pump area) as we are trying to determine pump or engine issue. Stuff a rag into the PTO.

About the engine maunts well they look fine but what would i need to check

I found that with the compression ratio and the air preassure in the atmosphere you aplay this fomula air pressure×compression ratio divided to the second number of the compression ratio you get the right compression on each piston so
792 mbar =11.487 psi
(11.487psi×10.6comp ratio)/1=121.76 psi
If i am right i dont have compression problems
Plase tell me if you agree with me

Grab the engine and try to push and pull it side to side. If you can? You have bad mounts.

OK I did it and I move the hole thing so no bad mounts

Based on what we know so far. I tend to agree. Learner key.

Hello again thanks for your help but i have checked with the dealer they brought the computer to my place and in the computer it says normal key he was not able to erase that key and make a new one and the sistem just had the lerner key and the normal key no high output key
can the system be wrong and even it is a normal key can it be limiting the speed???

Yes. They can be labeled either and have a restriction placed on them. Doesn't make sense they couldn't clear or reprogram it.
At this point, I think you need to prove the key is or is not restricted. You may have no issue at all. I take it you have only one lanyard?

Non-turbo charged 4-tech engines compression should be around 180 psi. Speed 35 to 40 mph..
Supercharged 4-tech engines compression is around 140 psi. Speed 60 to 70 mph. Miles per Hour...
What is the hours on your engine? Has it been rebuilt?
When the Supercharger fails the PWC loses speed and power.

Hello this pic has no SC and it has 100 hrs in it

135 psi compression is too low for your engine. Redo the compression check with engine oil squirted into the cylinders. If the compression does not improve, then you might have a valve problem.

Check the Sea Doo engine shop manual for the compression test and acceptable PSI. Maybe others might have an insight to your pressure loss. I am thinking your problem is in the top end.
* Blown head gasket.
* Bad valves
