3 litres an hour at 25 knts????
That's about 18mpg. Dream on mate.
I reckon consumption closer to about 3litre/nm is closer to the truth, with wot being more like 7-8litre/nm.
In per hour terms, I reckon you are looking at about 75litres/hour at a good cruise, 150-175litres/hour at full chat
I should say those figures are for dual engine, combined and consumption will always depend on Sea state and boat condition
