A nice thread - to confirm some of the items:

The Mount's engines are 1946 Enterprise, 615 HP each. 12 in bore, 15 in stroke. They top out at 450 rpm, but are normally run at a 400 rpm maximum. At that speed, she makes almost 15 mph with an average load. At so-called 2/3 throttle, or 300 rpm, she makes just over 10 mph.

The drive train is direct drive - no transmissions - so "neutral" is actually shut down. To reverse, the engines are restarted with the opposite rotation. Incidentally, she got new props two years ago. The old ones were originally 60 in diameter, but had actually worn down over the years to 55 in. The new ones are back to 60 in with much improved efficiency.

Also - great pictures! And yes, the man in the engine room is Darryl "Doc" Watson - now retired.
