David, See my post about my launch. Yes, loosen while under way, if you can do that safely and wait for a drip to appear while prop is spinning. Don Casey recommends one drip every 30 seconds. The box temperature is a good guide to prevent over tightening.
Because I installed a new stuffing box with new packing, I had it as loose as possible for about 15 minutes while at dockside to let water absorb into the flax, then I tightened it slowly till the drips stopped. I re-adjusted underway.

Aries splashed on Friday and I moved it to its summer mooring yesterday. I would some year like to make this trip with no issues, but so far it has never happened. 1. The autopilot circuit breaker popped every time I tried to activate it, so that is a project for the future. I presume something is frozen preventing the motor from turning the gear, although how that would happen sitting under a cover for a few months would happen is mysterious to me. I will disassemble (again) and try to fix it. 2. I tried to install the new Tides Marine track system on my mast. The test piece of track went in smoothly, so the size is right. But when I tried to install the actual track, the welded boom attachment fitting prevented a smooth entry of the track into the slot and I was unable to get it to slide in at all. Has anyone faced this problem and solved it? 3. The question I expect someone can answer is about the stuffing box. I repacked it with Gore packing and then hand tightened the collar while the boat was on the hard. When launched, I saw no dripping at all at the dock. After running for about 30 minutes there was still no dripping while motoring and the coupling was quite hot. How hot would this get if adjusted correctly? Should I loosen the coupling until it drips a bit while running? David Knecht Aries 1990 C&C 34+ New London, CT -------------- next part -------------- An HTML attachment was scrubbed...

Cheers, Paul.

I get a very occasional drip, and the packing box is cool to the touch after hours of running. I suspect that means yours is too tight. There?s lots of advice about Goretex on the web. The ones I read said that if the packing nut is too tight, you have to repack because the Goretex won?t expand out. I sop[pose it wouldn?t hurt to try, though, before packing. The good news is that once you get it right, you shouldn?t have to touch it for many years. It has been about three years since I had the hose changed on my prop shaft stuffinh box, and I have not had to adjust it once. Jack Brennan Former C&C 25 Shanachie, 1974 Bristol 30 Tierra Verde, Fl.

I have 1500 hours on mine. I let it drip a little bit, but not much. I probably should replace it, but you can't get it down here.
