@Justin_NSA correct. You hand tighten the nuts and lock them down. I do not have any water coming out of the stuffing box when the engine is not turning the shaft. When turning I get the occasional drip. I also have a tube that vents water from the Heat Exchanger into the shaft log to reduce the chance of an air bubble forming in the shaft log and overheating the stuffing box causing the shaft to get scored.
