That is the heater and control panel. It likely does not include the current drawn by pump motor(s) and accessories like an ozonator.

No idea, 40A would have been the right size. Could be the installer was used to installing 50A for tubs as that is the normal size circuit for a hot tub and just didn't read the nameplate. What size wire did they run?

Most control panels have the pump(s) included in them. All the ones I've installed did.
That’s what I was thinking. 6 I believe I’ll have to look

Is this a cord & plug unit?
Yea they want a 240 but the cord is hooked up to be 120

You would need to check and see if the tub is allowed to be cord/plug connected when run on 240V. There would have to be a circuit ran to a box with a 40 or 50A receptacle as you can't wire straight to a panel with SO cord.

Also have to be GFCI breaker. That 120V cord appears to have GFCI built in.
They can’t find the manual and I can’t find it online

I was going to run new wires car flex or seal tight and run it to a 50a gfci disconnect that has the breaker inside

They have a j box with the 50a circuit in it. I’ll just replace the j box with a disconnect box no ?

That's what I would do.
You also need to check and see if something like dip switches or a jumper needs to be changed to run it on 240V.

Yep, make sure it is within sight (50' or less) and no closer than 5' from tub.
So when I looked all I gotta do is put the other hot on line 2 to make 220 or 240.
It’s hooked up as 120v right now. Why would u need a jumper?

Probably not if the diagram doesn't show one. Sounds like you just replace the neutral with another hot on line 2.

A typical convertible spa can only run the heat on low pump speed, and heat at 1/4th the power (1.5kw).
On 240v, the heat and the high pump speed can run simultaneously, and can heat at full capacity (6kw).
There is usually a jumper for the control transformer, and wiring for the motor(s) for the supply voltage.
