We have had a "sqeal' too from the packing/bearing/shaft. Sometimes it's at 2100 rpm, other times it's at 24-2500. Annoying because that is right about where we usually run the engine. We have checked the cutlass bearing thinking maybe that was the problem, it's fine. No increase in the frequency of the drips at the packing. This has been going on for several years so it doesn't seem to be a major problem. Hopefully just some kind of weird harmonics.
