The LNVT wrench, mounted on the engine room's forward bulkhead, fits 3" and 3-1/2" nuts. The 3-1/2" fits the prop shaft's packing gland. The 3" fits the rudder shaft's packing gland. Several years ago Nellie's rudder packing started leaking badly. But then just as quickly it stopped. I believe the reason was due to water salinity—we'd gone from saltwater to fresh. The difference in buoyancy between salt and fresh water must be enough to move the water line from below the rudder shaft's packing gland to above it.
