hmmm, have a motor assembly which can hook up to the back of an old 72. 
Problem is that the deeper you go the less range you will have, torpedos 
were designed to run close to the surface. The classic torpedoes we see 
on the movies used a steam generator. And there will be an annoying blast 
of bubbles everywhere you go scaring the hell out of all the fish. And it 
would have to exhaust past the prop or you will get cavitation. Batteries 
are looking better and better.
