Steve, Raw water intake is drawing water in by means of a pump...no such
mechanism is involved with a PSS seal. Bill Walker CnC 36Pentwater, Mi.

Bob,
In the 20 years I've had my C&C27, little bits of wood or twigs have got
sucked into the engine cooling water intake on several occasions and lodged in
unobvious places. They caused partial blockages that were hard to diagnose and
are memorable for that reason. Our sailing club is small river leading into
Lake Erie so there is a lot of crap being driven down steam from time to time.
Count yourself lucky if you don't have that problem.

Fred:
I’ve never heard or imagined anything so strange. First, the shaft seal is a
good foot or more below the waterline. Pieces of wood generally float—so they
would normally be near the surface of the water. And then have a piece of wood
lodge between the stainless and graphite seal on top of all that! I would think
the odds of that happening by natural occurrence would be astronomical.

Years ago a small piece of wood came up thru the shaft log into the bellows
and wedged itself between the stainless and graphite rings. The boat sank
overnight. The moral of this story is that you should periodically check the
pressure of the bellows. My stainless ring had slipped.

Jeff,
As you mentioned earlier, this topic shows up every so often.
As a PSS user, I am obviously biased.
The stuck graphite face was an issue in older designs (the unvented type). The
Volvo version of the dripless seal still requires burping.
I can imagine that if I were to sail around the world, I might prefer the
traditional stuffing box (the maintenance is easier and the spare parts can be
fabricated by a skilled blacksmith (😉)), but if you sail in the area where
spare parts are generally available, the dripless solution is completely
reliable.
I am happy with my dry bilge.

Let's exclude power boats -- an entirely different environment and demand on
the hardware.
