This is the best impeller wrench I found (for the OEM impellers with the neck):

For the impeller wrench - many use a large crescent, which usually works. But if it is on really tight, may round the corners and slip, these impellers are not made from very hard SS. If you can find a box wrench for the impeller - I think it is kind of between 26-28 depending on where you are on the neck...
You may be better off with one of the "adjustable" wrenches like this - this is my go-to tool for OEM impellers:

You will also need a big vice and a cheater bar, a big one, lol.
