Additional Description
PSS Propeller Shaft Seals:

A mechanical seal is created by the contact of a turning surface against a stationary surface. In the case of the PSS Shaft Seal, the stationary surface is a carbon flange held in contact against a stainless steel rotor which turns with the shaft. The carbon flange is attached to the boat by a nitrile bellow which, with the help of water pressure, produces a constant contact between the carbon and the stainless steel ring. These type of seals are unaffected by engine motion or vibrations. The result is a 100% watertight and totally maintenance-free seal.

PSS Shaft Seal

I have a Riviera launch with 2" pss dripless shaft seals.
On one of them I have wear on the grahite seal. Can I just replace the graphite or do I need to replace the whole unit ? Is it a big job to just replace the graphite seal ? I assume the boat has to be taken out of the water and put on the hardstand?

Yes, this PSS Dripless Shaft Seal can be replaced, and yes, you will need to haul the boat to do the repair. You are looking at about .00 in parts.
