I guess that would depend upon the configuration of the stern tube.
I had one on my old C&C 36 and never had any trouble. Just
installed one on my PO so the jury is out on that. The moral is
to burp it after any prolonged rough sailing. I would have preferred
the one with the injection feature, but it wasn;t available in my
size.

One problem with the original "low speed " version was that not only
did you have to burp it after a haul out, but if you were rolled by a
severe wake or unusually choppy seas, it was possible to uncover and
drain the shaft log. If you were unaware of the situation, your seal
would begin to run dry and hot. That is why PSS discontinued the "Low
speed". They even kicked in 1/2 the price of the new seal when I
complained.

One disadvantage to the tubeless one is that you
need to burp the seal to get the air out.

I thought this burping was only after the initial installation. Surely
you
are not expected to burp the seal before every use of the motor? Someone
being extra cautious here?

FYI PSS no longer sells a low speed version. They only sell the water
injected "High Speed". If your application originally qualified for
the "low speed" version, you can safely use the water injected unit
without hooking it up to the cooling system. Just attach a 3/8" hose
and bring it high up on the centerline as a vent. No burping and no
compromise of your cooling system.

I solved the problem and kept the injection. It simply has an inline

shut off and forgotten like the tubeless one after that.

Larry, are you going to write to PSS about this whole thing and ask
their opinion?

I would have thought that would have been one of the initial steps
towards a solution.
