[PSUBS-MAILIST] Pressure proof motor

[Alec Smyth via Personal_Submersibles]

Hello Friends,

Cliff and I have a joint R&D project this winter to adapt higher
performance lip seals to the Minn Kota 101. The seals themselves are custom
made by Parker and have a lead time of several months. We haven't received
them yet, but at least according to Parker's specs, they should enable 101s
to become 1-atmosphere thrusters to pressures that exceed typical PSUBS
depths. They also should minimize friction under pressure, compared to the
stock seals. We'll keep you guys posted...

Best,
Alec
