I own a 1990 Hunter 28. While the engine is running the stuffing box is leaking a small but steady stream.
or a steady drip? While the engine's running, or when the prop shaft is turning? It should drip every 10-20 seconds when the prop shaft is turning. It has
to, to provide lubrication and cooling for the packing.
Anything I can do to temporarily fixed the leak? Does it sound like it can wait till end of season?
If it's more than a drip every few seconds, you may be able to simply tighten the packing nut up a bit
. It all depends on how old the packing material is and whether that's already been done. Otherwise the packing material will need to be replaced. Either way: It's not really a difficult job. See the material sailingdog pointed you to. Suggest using Gore GFO or GTU packing material. (The latter is available at West Marine.)
