Logic says that since only about 10% of the chain is resting on the sprockets, then this is not the actual pivot point for the chain. I believe it is just a chain tensioner we are seeing to reduce flex in the actual chain run. It looks like the actual load bearing drive sprocket would be about a foot (or more) in diameter and located inside the limits of the chain guard guard that is showing in the top right?

As for it's application? I don't know.
Lifting relatively small (as far as Navy boats go) boats out of the water?

Wierd thing is, if it isn't a torque transferring sprocket (just an idler or tensioner), why is it keyed?

To run the shaft on the bearings so they don't put wear on the shaft itself.

Setscrew wouldn't do the trick?
