Check out www.parkerseal.com.  I think what you want is 2 rotary lip seals; one facing in for the compensation, and one facing out, just in-case the compensation fails.  You can write they tech people and they will help you select the proper seal for the psi, shaft, rpm, etc.

I don't know about the thrust bearing. I think it depends on what the motor was originally designed to do.

Subject: [PSUBS-MAILIST] motor pod seal

I am trying to figure out what to use for a shaft seal for my main motor

 

I am planning on manually pressurizing a pod made from and air compressor

tank. So I guess what I am looking for is a shaft seal that will take up to 200 psi

internal pressure, this is way out of my expertise.

Any suggestions on what to look for

 

That and do any of you use bearings for the propeller shaft? All I seem to see

are just bushing types, I am using a 12hp dc motor and it seems to me that a

thrust bearing is in order.
