[C320-list] PSS question

[Bruce Heyman]

Hi Greg,
I have no idea but I don't think it takes much to allow the mating surfaces to be running dry.  I also don't know if the turbulence of the spinning shaft doesn't eliminate the air in fairly short order.
Best,

I wonder how much air ends up there after the diver cleans the bottom.
