I have Duramax packing and may have overtightened it the first time out, which I’ve heard can cause problems. So I had it replaced and both boxes still leak if they are loosened enough to prevent overheating. As for grooved shafts, I was making an assumption. I worked a fine tool inside the stuffing box while on the hard (with the packing removed) and didn’t feel much, if any, scoring but I’m not sure what else could be the cause. I’ll continue to play with the adjustments, but will also use the collection tray/mini bilge pump setup. Will let you know how it works out.
Thanks again for all the thoughts.
