[PSUBS-MAILIST] Motors filled with OIL

Tarek,
I built a very small dry ambient submarine using inexpensive Chinese
electric trolling motors. I air compensated the motors & hull using
slightly modified octopus regulators.
The motors for my next submersible will be oil compensated.
My project is under ambient & Alan James on the psub projects page.
Let me know if you need any more help.
Regards Alan
