Re a Nordic Tug 26 with Yanmar power and traditional shaft seal. During a first-of-the-season run yesterday to check things out I took the temp. of the shaft seal packing nut. 95'F. There was, however, more water dripping - 10-15 drips per min. than I would like. Today I intended to tighten the packing nut a 1/4 turn or so but didn't as there wasn't any dripping with the shaft stationary. My understanding is that 95' is a good running temp. and that no drip when not running and 3-5/min. when running is the target.
Regarding the attached pics, my concern is about the material I found in the bilge below the packing nut—the material on the towel. I looks like pieces of packing material.
So my questions are: 1. Should I be tightening the packing nut to reduce dripping when underway even though there isn't any dripping when not running? And, 2. Should I be concerned about the bits of material found below the nut? I guess there is a third question - Am I being overly cautious about this?
