Very interesting, I don't think I'd like to work on one. I think I remember a video of a big one from a ship.

About one third of the WW II diesel submarines were outfitted with Fairbanks-Morse 9 cylinder (and later 10 cylinder) opposed piston engines.  They were running fools.  Served on one with Fairbanks and 3 with Jimmies.  The Fairbanks would outrun, outlast and require far less attention.  Biggest fear was water seeping into the cylinders and causing a hydraulic lock that would bust the vertical shaft that connected the two crankshafts.  Sadly Fairbanks Morse went out of business.  Side note: the locomotives of today have the same propulsion system (diesel/electric) and same engines as the old subs.

A lot of information there! A WWII Submariner? Or even serving later on one of those subs? God bless you. I'm too big of a sissy for that. I'll see what engines are in the diesel/electrics that the V&T uses. A good friend works in the shop there. Maybe I can learn something. I had a bent rod from one of their diesels and thought it was kinda' short. I used it on a trophy. For some perspective the wrist pin is the sleeve from an old shock. The piston is from something else.
