OK now i know this post is quite old & you've long since solved your problem but ive taken it upon myself to do the exact same thing without buying expensive purpose-made stuff, just to use the stuff i already have lying around or cheaply bought!

Stumbled across the link below that ive tried out and it works very well, i can settle for a 95% waterproofed shaft seal as my little project is making a liquid pump, but its a very good way of keeping water/liquid out the motor!

I also will be making a submarine next year some-point so i'll try to reverse-engineer an expensive-type shaft-seal (on the cheap of course!) as long as i can find and understand the basic principal of one online, i mean, the schematics gotta be on the web somewhere !

Hope this helps you & everyone else!
