Can anyone recommend some good 12-volt motors that can be used underwater, from a place that will ship to Canada? The smaller the better (but no nanobots please Razz).

I would seal it in a plastic or metal tube using epoxy or silicone. Go to Princess Auto, they have some great motors.

The idea is to spin a small blade underwater. How would I seal the motor while still allowing the shaft to turn?

You could use a rubber washer that is slightly lubricated so that it doesn't melt with the shaft rotation. I have never done it but I think that should work.
