It should drip 3 to 5 times a minute when the shaft is turning. The stuffing box should not feel hot to the touch when running. It should not drip at all when the engine is not running.

Shaft Log Drip: What's acceptable?
Any ideas on what an acceptable drip rate is on a shaft log? It's been dripping since we bought the boat new, and I had it adjusted at the 50hr tune-up, but it now leaks (after working the prop shaft) at a rate less than 1s, and (after several days' rest) at a rate of 22s.
At what point does a repacking become necessary?
I'm working with a marine gear on a Yanmar 30
