Not sure about the shaft length, but it is only supported by the strut/skeg near the propeller through the cutlus bearing and tgen again by the coupler at the gearbox.
PSS is a brand of Dripless Shaft Seal. There are two methods of passing a shaft through a hull; Suffing box, or dripless shaft seal. PSS is a popular brand of dripless shaft seal. That simply allows the shaft to pass through the hull while preventing the ocean from entering the hull through the same hole.
If the shaft were too long, then you would be getting flex. If you were getting flex you'd be wearing out the cutlass bearing in the shaft strut prematurely. I doubt you need another shaft strut.
