We had a similar "whine" that eventually disappeared.. then the stuffing box drip rate increased. Repacked the stuffing box and now that whine is back at the same rpm.. so I suspect that's the source.

It's not a big issue for us as we rarely travel at that particular rpm, I just hear it briefly as we're slowing down to enter our marina. Beyond the temporary noise, the stuffing box drip rate is fine as is the running temperature.
