[PSUBS-MAILIST] Motor modification

[Antoine Delafargue via Personal_Submersibles]

Hi frank
I have done something like that for my prop shaft seal oil filled
compartment.  But first i removed the hose and filled with a serynge with
long steel needle. Then put the tube and filled it with the serynge.
The tube is flexible and transparent, from endurance sport
platypus drinking bladder
Works well
Regards
Antoine
