Soundings just had an article on a guy who replaced older gas engines with
diesel. He saved thousands on fuel and picked up a fair amount of range

Is it cost effective due to the higher price of diesels.

It depends of course on how you calculate cost effectiveness. This
particular boat was a planing boat, and the increased efficiency of the
diesels allowed the boat to carry somewhat less fuel, making it lighter
& easier to plane, and increased range at the same time.

The engines were expensive, but over their expected service life they
will more than repay the greater cost *if* the owner often uses the boat
to go longer distances in open water, as planned.
