stuffing boxes? I was wondering if anyone has replaced their seals in their stuffing boxes?
just looking for advise on this before I dig into this project. is it as easy as it sounds?
remove the stuffing box nut dig out any old stuffing and wrap the new cord (stuffing) around the shaft
then crank down the nut? by the way it's a "85" 34 ft searay express. go on i know it all sounds funny

You may have better luck getting a serious answer in the Cruising / Power forum.

I think if you crank your nuts too tight you will bind your shaft.
Too loose and your shaft will leak.

Let me know how it goes. I need to do the same thing soon.
I wanted to do dripless shaft seals but they are too expensive.

And I don't think I want to know why there are seals mentioned in this twisted post, or why they need to be replaced. Did you wear them out??

well, on a inboard where the shafts go through the hull
there is the stuffing box that is packed with a cloth/wax
type cord. this works as a seal. the newer boats have
a regular type seal.

Just did mine this week. Hardest part was getting the old stuffing out. Fortunately had the tool for it. Repacking was easy. Waiting to go in the water will tighten at that time if need be. Mine is an 86 Searay express. Easier than I thought.

your'e just a little bit off. The rule is if you crank your nuts too much you'll go blind. Regardless how tight you hold your shaft.

Make sure you get the correct size packing. Don't wind it on the shaft. Put one band on at a time and cut the packing on an angle so it will seal back together. Also stagger the the bands where you cut them (i.e. - if you install 3 bands seperate where the seams are by 120 degrees). Only tighten hand tight. You will surely need to adjust the stuffing boxes once your in the water and after your first couple runs out. You want them to drip about 1 @ 20 seconds or so. Good luck.

Do you count the drips while the shaft is spinning or at rest? We put our boat in the water two weeks ago and the shaft seal was pissing like crazy while it was spinning. At rest is had slowed way down. What is the correct way. Thanks.

I watch the drips after I ran the boat a while and everything was well worn in. It will take a few trips out to get it adjusted to where you feel comfortable. The last thing you want is the stuffing box to get to a point where it is too hot to touch. If that happens you could end up burning marks into your shaft.
