Thanks for all the replies.


It would appear that the bellows may take a few more yars, my Nt is only about 600 hours running, the risk is, of course, mine.


A nice cruise for everyone!

This issue is more related to age than operating hours.
Agree with Ski, if its still flexible its probably ok

Hard durometer, thick "rubber", and compression make it difficult to determine whether bellows is hardened because of deterioration. Look for micro-cracks. Might be easier to tell if compression is released next time out of water.

A good bright LED light will illuminate the PSS quite nicely for a visual. Yes, the bellows will be "stiff" since the material is designed for below the waterline use. Even when new they will appear stiff to some.
