[PSUBS-MAILIST] second stage adjusting

[Rick Patton via Personal_Submersibles]

Hi Emile, not sure what you mean by open door? My second stage is probably
18" to 24" lower than the thrusters but someone in the group said that he
had adjusted his second stage I thought to more over bottom pressure than
how they come off the shelf.
