I had the same issue. Tighten it o so slightly and you will be fine. After doing so while under way touch the gland , if its hotter than jacuzzi water, its too tight. I get about 4 drops a minute but don't be concerned if its 12. My bildge is bone dry always. I keep a rag by the water intake. After a day of sail and motoring I have a damp/wet cloth. After my keel bots started to show signs of rust, I was focused on water not getting into the bildge accept on long trips. I chipped away the white resin around the blots/washers and now it looks super clean and I can see what happening if anything.
Remember, a little tightening does a lot, so go slow!

The manual says to tighten the packing nut on the prop shaft to get a drip rate of 4 to 10 drops per minute with the engine off. When I had been running and shut the engine off I observed a very fast drip rate...perhaps 50 drips per minute. When I went out to the boat the next day with the tools and manual to make the adjustment it was only dripping at about 6 drops per minute. I started the engine and ran in gear for about five minutes under load at the dock. I shut the engine off and again I observed a rapid drip rate of 50 dpm or more. I know that I should not over-tighten the packing nut so as to avoid running the shaft seal dry which can overheat the seal and wear the shaft. I left it as it is because I don't know whether to tighten it some or just wait for it to slow down as the boats sits at rest. After a day of sailing that ends with motoring into the marina, I find that I do have to do about 10 or 12 strokes on my Whale Gusher manual bilge pump to empty the bilge. Should I tighten my packing nut some or what? I would appreciate some advice.
