OK but the description says that the motor was tested to draw 3.5 amps with no load
That implies that it draws more than 3.5 amps under load. Which is likely.
However, I doubt that it's 3x as much. the 10A supply should be more than enough.
It would just be nice if someone with EE training would chime in.
oh, and no, you can't reliably combine two 2A supplies, but having more amps available isn't going to hurt anything if you get the 10A.
You could probably shoot for 5A and be ok, but i don't really know.
If the OP has a car battery and a DC ammeter around, he could build his mash tun and then find out how many amps the motor draws, and then find a suitable supply. In general you want to shoot for a supply with some headroom over your measured current draw, just in case. like 30-40%.
