Does the impeller supposed to spin freely

No. It should not "spin" because it is geared to the crankshaft. You might get it to move back and forth a degree or two.
If it spins, I think you have found your problem. You have a "chipbox" instead of a gearbox.
That rock was enough to cause issues. You sucked it up. Too shallow.

Is the pump still in the boat?
If it is out then it should spin freely.
If it is installed it should not.
I assumed it was out.

Its still in. I just took the end piece off, As I was only being held in my one bolt. as it was only being held in my one bolt I just want to get four more bolts and put it back together and see if that was my problem
What engine/year do you have? Please refresh your symptoms.
Is your stator still off? A 2-person test of the gearbox:
One person at the engine with a socket and ratchet to fit flywheel nut. 2nd person at the impeller. Try to turn the impeller against the engine. THIS IS NOT A BRUTE TEST. If the gears are bad, it won't take a lot of force to show it.
Of course, key off, kill switch off.

if that utopia M2 240 has the same pump setup as my 2002 challenger M2 240- it doesn't have a replaceable wear ring like the rotax engines have- it's a one piece machined aluminum part- I was never able to find any after market parts for my M2 jet pump- you may find used parts in good shape on ebay. in the $1500 - $2200 range. It's one of the reasons why I stay far away from the old challenger M2 boats. I've owned 3 of the 240 M2's and nothing but expensive issues. If the wear ring isn't too bad, you might be able to have it cleaned up. You won't find any Mercury M2 parts from Seadoo because it's not a Sea Doo product, it's a mercury product. Here's the entire pump assy on ebay- price isn't too bad considering you're getting the whole jet drive-

This place has a nearly new complete pump

However- most on this forum fix their wear ring the cheap way- fiberglass and epoxy. About $20. My repair has been good for 4 years so far. There are shops that will machine and install a stainless ring for about $500.
As for the stator- the rocks got sucked up and blown thru the impeller. Can you use a dowel rod from the aft end and tap them out? When you get them out, some Dremel work on the vanes might be indicated. Looked like your impeller could use some love, too.
