Or does it work like an aquarium pump I used to have -- which had the staionary magnetic coil part of the motor sealed in epoxy inside the case, with the case "donut" shaped so that it wrapped around the shaft on the out/water-side of the case?

Either way works. I suspect that the latter is the way most do it, as it
would make the thruster easier to streamline.
