What a chore! Having her on the hard for repairs was a good time to re-pack the stuffing box. I first squirted some WD40 on the jam nut and tapped on it a few times with a hammer. Returned later, but it would not budge. Even with another pair of hands we could not break it loose. Then I squirted some Liquid Wrench on it, tapped it a few more times and returned an hour later. WahLah! The stuffing box is hard to get to on a P42, but I was able to get a good pull on the nut from the small access door at the bottom. It took about 30 minutes of picking with a dental pick to remove the three layers of 3/16th inch flax packing. I only hand tightened the stuffing box so that when the boat returns to the water I can tweak it before locking to make sure I have the right drip rate. Too, tight and it can burn the flax and destroy its' sealing properties. Terry S/V Belle-Vie Terry
