[C36IA] Stuffing Box

Wed Jun 3 17:40:28 EDT 2009

I always get a little of the black liquid from the Goretex packing material
(leaves a little racing strip athwarthships).

To adjust, I¹d suggest tightening the nut to the point where you get just a
few drops of water dripping from underneath the nut. Then run the boat and
carefully feel the temp of the packing nut while underway.

If the nut is too tight it will feel warm. When the boat is stopped, backoff
a quarter turn and try again until you get the right balance.

I just live with the few drops and a cool packing nut.
