Steam powered submarines eh? just some tinkering here,its the motor for my next tin boat. The K class killed more of our side than the Germans! The motor took 2days to build from scrap. just got to figure a way to clutch in the clockmotor for diving. Boringly enough,the earliest subs were steam and so are modern nukes! ahhh the irony. Ohhh it runs like squit off a shiny shovel.
