Dripping is now normal or what you guys describe as normal. Sound/squeal is definitely from shaft but no overheating of stuffing box or shaft when it is happening. I can't find any evidence of when packing was last changed so figure I should redo, start all over. The boat was just pulled this past November for bottom job, replace seacock, etc. Dont want to pull it just for this.
New mental picture...me standing on dock next to boat which is now sitting on the bottom. I'm mumbling to no one in particular... "Shoulda had it pulled."
Are you going to use the Gore fiber?
Do not use the old style flax packing.
It drips lot, can run hot and score shafts, it just is inferior stuff nowadays.
Over 10 years ago, I used Gore GFO marine packing on my old scored dripping shafts, and it has been perfect ever since. I tightened it up about 3 times.
Prior owner who used the old flax packing could never stop the shafts from spraying lots of water, was constantly adjusting the packing, and worried about it too. When I got the boat, there was a steady spray of water soaking everything down there.
