If it looks like the second link K1W1 provided, it is a PSS style. The rotor is on the right side of that drawing, it is secured to the shaft. The corrugated looking bit on the left is rubber or plastic and connects to the log. The intermediate part with the tubing barb sticking up is the stationary part of the seal.
The instructions for checking with an indicator apply to the seal shown in the second link.
Do you by any chance have a standard packing gland that is mounted forward of the log by a length of stiff rubber hose and not a mechanical (dripless) seal?
Or is it maybe one of those "bluewater" things that has a lip seal inside a housing that looks like a standard stuffing box connected to the log by a short piece of rubber hose?
If it is one of the latter, your shaft is either bent or it's whipping and the lip seal won't last long either.
