[PSUBS-MAILIST] Thruster

[Rick Patton via Personal_Submersibles]

Alan, My second stage is located as low as possible but Alec has the same
exact "I followed his design" system and he said that he had gotten some
water in the thrusters as well as the accuators, plus I was thinking that
the force of water being as dense as it is would force it's way down the
tube as the water burbles over and around the mouth piece and there is no
resistance in the lines or housings to prevent that as they are at one atm.
