[PSUBS-MAILIST] Gauge for outside viewport?

[hank pronk via Personal_Submersibles]

Alec,
I am driving Gamma with two Perry thrusters that have a simple mechanical seal.  I think a Minkota could be modified with a mechanical seal.  A new end cap and a shaft extension would do it.  This could be a add on kit for Psubbers.  I can send you pictures of the Perry seal set up.
Hank
