Is my Impeller toast

[platinumtron]

Had to replace carbon seal and wear ring so i figured i would go ahead and check everything else to include rebuild the pump. When i finally got the driveshaft out of the impeller i noticed some severe corrosion inside. To the point i think it may now be hollow once i remove the impeller from the impeller shaft(tool should be here tomorrow).

I would like to know, does this look serviceable or should i look for a replacement?

If serviceable, should i put an acid in the spline area to remove the corrosion and then pickle?

Throw it up and if it lands butter side down it's toast.

I would just clean it up, the splines appear to be ok.
