Look in your Yanmar manual !
Your naturally asperated 1GM8 should be similar to a YSM8 that has 331cc displacement. The YSM8 manual states the fuel consumption (at full motor load and full load RPM) is 1.8 liters per hour. My YSM12 has a book value of 2.8 liters per hour but I average about 2 liters per hour at 2800 RPM (5.5 knots) cruise speed. It has nothing to do with boat and/or propeller properties. Fuel consumption is proportional to motor displacement, motor load and motor RPM. There is formula but I don't have it handy. Don't ask me to translate liters to US gallons.

Thanks for your helpful information.
Yes, the reason I am asking is because I do not have a manual handy and haven't use the boat yet.
Can you please translate lters to US Gallons?...just kidding 1.8 liters is about 0.47 gallons.
Cheers!
