Transmission - Looks like a chain system in the lower right of this pic.
Turbocharger System - Looks like the "Plenum" is the polished tank up in the right corner of the same pic... The cutaway shows a circular device of some kind that feeds this plenum... that must be the turbocharger system. That fucker is nearly 100" from top to bottom when comparing it to the 98" stroke!

There are no transmissions on ship propulsion units, just a direct drive from the crank to the prop. For neutral, they shut the engine off (hardly ever). For forward, they start it up. For reverse? It's a two stroke for a reason. You guessed it... they start it backwards.
Mercury had a similar setup in one of their engines back in the `60's. It was an inline six outboard that shut off when you were in neutral, started up when you put it in forward, and started up the opposite way when you put it in reverse. It didn't always start, so it was aptly nicknamed The Dockbuster.
On gas turbine and steam turbine propulsion units, it's a different story because the turbine only spins one way, and they need a gear reduction box to turn the 40,000 RPM turbine shaft speed down to 75- 125 RPM prop speed.
And Steve- you sound like a nautical ricer. Shut up, will ya?
