Hi Bob -
You are right about running GMs (DDs) often and hard. Screaming mimis.
Not sure how you figured out how to save 25% on fuel. I worked for a company
who had identical boats operating on identical routes. Some had 12V71N GMs
and some had 3408 Cats - both rated about 340HP. I always preferred Cats, and
I kept hoping to prove that the GMs were less efficient, but the difference
in fuel consumption was too small to measure. What finally won the day, so to
speak, was the difference in time between overhauls. But that was because the
GMs could not deal with idling. Keep 'em hot and working and they are a
great engine.
Regards,
John

> Fuel burn on the 160 hp x 2 is slightly less than 8 gal/hr, but that
includes genny. I think I figured out that I could drop that 25% by going to
4-stroke diesels.
