Fuel Consumption/ rpm

[php1950]

Good day!
I have a Mercruiser 5L/LX - 205 HP in a 1993 20' Mariah bow rider. I am interested in calculations for fuel consumption gal/hr at different RPM settings. Does anyone know where this chart/information is available? It seems my 20' bow rider likes around 3800 rpm for general cruise power...
Thank you.
