> A troubling stuffing box situation began last week (and continues): We ran the engine reasonably hard for about 4 hours when doing the NYC East River trek to Long Island Sound. I was in the galley when Keith raised the sails and cut the engine (leaving transmission in neutral). Immediately I heard water pouring into the boat from the stuffing box area. I shouted for Keith to throw the transmission into reverse. No more water! Whew! Water quickly exited the boat via bilge pump - with the exception of 10 gallons sitting under the engine that I had to pump out by hand. Diagnostic guesstimate #1: New zincs on the prop shaft causing wobble that is stressing the 2-year old flax packing gland... right? The cutlass bearing is fine. Other thoughts: Folding prop has inherent balance issues, engine/transmission/prop shaft alignment fine tuning necessary, packing glands wear out quickly under stress?? Would anyone like to tackle this one?
