Lesson learned the hard way"
#1) Wait/read the manual.
#2) take picture as you proceed so you know how to put it back together.
We've all done them in one form or another.
I don't know if it will come out without taking the remainder of the bolt out. Janey ran into the exact same problem. Don't know if she ever resolved it. Depending on amount of thread/bolt exposed you mat have several options.
1) Drill a slot in the bolt with a Dremel and see if you can get it out with a screwdriver.
2) Weld a nut to the remaining bolt and see if you can now get it out with a wrench.
3) If the bolt broke beneath the surface of the impeller and it broke in such a way that there is a surface you can catch a punch on you might be able tap the surface at an angle with a hammer and punch with the vibration of hitting it, it might work it's way out. That is how we used to back out bolts (albeit much smaller) at IBM when they broke below the surface. There may be a problem with gear teeth though.

Before you wrench, tap, twist etc. make sure you're going the right way because if you're not deliberate you may find yourself going the way you're used to (the wrong way in this instance).
