This guy has designed and built a model MagnetoHydroDynamic (MHD) boat that's silent, practical (no ducts) and well; just plain interesting science!
It's not fast or efficient, but does beat the very few other (ducted) designs online.
NB that the hull is designed to be optimal for low speed and mid mounted thrust Its not just about the drive.
If you want to sneak up on fish and not worry about prop fouling this is an option.
Perhaps a good secondary drive option and a great way to cheat the hell out of races!
Here are his videos filtered for 'MHD':
I enjoyed watching them all (learning) and gained an understanding/appreciation of the science and just what he's achieved here.
I cant help wondering what would happen if this were built into the suction side of a propeller to minimize cavitation and tip vortices..!??
