Volvo Penta Aq 145 petrol engines

[GuyKilbey]

Does any one know what sort of gph should be getting from a pair of AQ145 petrol engines in my princess 30ds. I know it depends upon a number of criteria and am only looking for a ball park figure

If it helps, I used to have a Princess 30S - same hull, similar layout - with twin AQ145a engines, and used approx. 20 gallons per hour at 20 knots.

Fairline Sunfury (26ft ~ 3.5T) 2 x AQ145b = 75 litres (~17Gal) / hour @ 23kts.
