I have a drip from my packing gland with the engine off at approx 20-30/min. On sailboats I've owned in the past, the stuffing box had a rubber boot, a single compression nut and a single locking nut, both around the shaft.
The set up on my MT is below (sorry for the sideways picture, the boat is actually keel down in real life <smile>). No rubber, two nuts and no locking nuts.
I am assuming all that I need to adjust this is to slightly tighten each of the nuts on the "yoke" a 'smidge, equally, correct? I am going to pull the boat for bottom painting in a couple of weeks and will likely repack then.
