Hello, Matt, it is a great day here.

 MM> AFAIK, the newer ship engines no longer shut down and start up

        OOoooohh ! Are we ever dating ourselves here.

 MM> The ratio on the marine units is usually very close, ie: 1.2 to 1,
 MM> 1.1 to 1, etc.  Don't believe I've seen any greater than 1.5 to 1,
 MM> and that was in very small stuff like tugboats.

        IIRC, my sloop was at 2.3 ratio. It had one of these new
        generation small/efficient diesel, it ran at 2300 rpm at best
        mile per gallon setting. Mind you, it had to do with the hull
        shape and all.

 MM> I also saw lots of them in the 'junkyards' in Vietnam, and I believe

        It made for a very smooth trany. And a Huey needed some.

        A great day to you.
