How much fuel do you use?

George Isted at 22/02/2011 13:47:36
Hi all,
I’m just trying to work out some rough numbers for my engine and wanted to compare to others experience.

Concerto has a 2GM20 (18hp) and I have always worked on the basis that it uses around 1.5l per hour at cruising speed (5.5kts ish) does this sound correct to you? I think the standard (1978) tank holds around 50 Ltrs so that gives me 33hrs of motoring. Cheers

My 2GM20 uses 1.1 litres per hour. this has been calculated with many tanks of fuel. 1800 to 1900 RPM. Big 3 blade prop to load it up as well.

We use about 1.5 litres per hour at 2100 rpm with a VP 2002 with a 2 bladed prop.
