[PSUBS-MAILIST] motor oil compensator

[Øystein Skarholm via Personal_Submersibles]

You should avoid contact between the seawater and the oil. The oil will
contaminate quickly and it will no longer be dielectric.
Just the hose from the motor to the tee is enough to compensate. You do not
have to have a large volume of oil. Fill the hose with oil and cap it off,
done. or make a neat yet more sophisticated solution.
Make the end lid of the motor as a flange assembly and instead of a lid,
use a rubber diaphragm. This will then act as a compensator. You can even
install a light spring pushing down on the diaphragm  if you want a slight
internal overpressure.
