[PSUBS-MAILIST] thruster vacuum fill

[Sean T. Stevenson via Personal_Submersibles]

You mean pull a vacuum on the motor housing before admitting the
compensating oil?  That would certainly minimize the possibility of
residual air bubbles, but with appropriate volume available in your
compensator (to accommodate both compression of residual gas space, and
thermal expansion / contraction), even that shouldn't be a problem,
should it?
