Re: [PSUBS-MAILIST] Oil vs air

["Paul Suds" <paul_suds@hotmail.com>]

On my DPV, I used a high quality rotary seal. Does anyone use an oil filled 
motor housings on any of their shallow subs or ROV's? I know this question 
has come up before, and I've always advocated air with a good rotary seal, 
but I've been doing some research on Navy rotary seals and the like. It 
seems that the really deep ROV's and some subs use high dialectric oil with 
pressure compensated diaphragms. My motors are going to be kind of 
expensive,high current, and high voltage. Oil is starting to look 
desirable...Suds
