Fuel Flow Consumption

Anyone know a good source for finding the fuel flow or GPH at various RPMs?

Just looking for some ball park numbers for a 1999 Carver 504 with Cummins 8.3 engines (450) HP.

Our fuel gauges are lying to us - shocker - and I need some guidelines while I sort things out.

This should be a good place to get a feel in broad terms

When I was researching my purchase I referenced these guys because they do list rpm/speed/fuel burn in their reports. If they have your model or one close to it, you can likely obtain a report although it may cost a few bucks. It may be worth a try for the ballpark range you are seeking.

Try Boat fuel economy.com. It allows you to select your engines and provides the info you looking for.
