particular boat was a planing boat, and the increased efficiency of the
diesels allowed the boat to carry somewhat less fuel, making it lighter

In general, a diesel engine weighs a lot more than a gas engine of the same
horsepower. I would think that you would have to be talking about some very
large fuel tanks to have the fuel weight significantly counteract the engine
weight.

The weight difference isn't *that* much. Maybe a hundred pounds or so
more per engine for a typical setup, give or take. That's only like 16
gals of fuel in weight. When you're talking about tanks of even only 50
gals or so, you can easily cut out 16 and still have the diesel get the
same range. For larger tanks, the diesel will have more range for 16
gals less fuel capacity.
