Re: Send packing the stuffing gland..
I've had a PSS shaft seal on my boat going on eight years. I plan to do the six-year maintenance this coming fall. Never had a leak or any issues at all except one:
The shaft seal requires lubrication in the form of raw water. You'll see a hose fitting on the PSS shaft seal on the forward end. This allows a hose to be plumbed into your raw water system so that the shaft can get some raw water when the engine is turning the shaft. When the engine is not running, this hose can allow raw water to run the other way - from the shaft seal to the engine raw water system. Several years ago, I discovered sea water in my crankcase and finally figured out the water was coming from the shaft seal. Since then, I've raised the hose and installed a siphon break, but a check valve might work or even a regular valve that one closes when closing off the raw water thru-hull after shutting down the engine.
