Hi Dennis:

The fuel consumption chart for the Yanmar 3gm30 goes from .4 gallons an hour at 2000 to 1.6 at 3,400. At a cruising speed of 2,800, you get about .89 gallons an hour.

This gets a little tricky because you don’t want to run the diesel too slowly. That encourages carbon buildup and hastens a rebuild. Diesels want to be run hard to be long-lived. (I.E., 10,000 hours or more.) Better to burn a little more fuel and have a happy motor.

If you’re running slowly for some reason, get to an open stretch of water and crank it over 3,000 rpms for 10 minutes or so.
