The problem is usually a leaky shaft seal kit, shown here as Items 7 and 8 (click the pic for the larger, annotated view).

Fortunately, the shaft seal kit is inexpensive; but it can be a booger to install, depending on how much rust you’re dealing with. May require a destructive removal of the impeller, too, but ain’t no thang ‘cuz the shaft seal kit comes with a new impeller. Here’s a nice, purdy picture of a brand new shaft seal kit.

So you go ahead and drill, cut, and chisel all you want on that old impeller!
