That's quite usefull info. do you happen to know if thats imp, or US galls?

Also, don't suppose you'd have any figures on the Yamaha 250 fourstroke?

DOH forget the Q about imp/US galls!

'According to that report, fuel consumption for the F115 is as follows:

RPMs GPHs
1.0k 0.7
2.0k 1.3
3.0k 3.0
4.0k 4.6
5.0k 7.1
6.0k 9.8

At the mid point between each of the RPM ranges, I estimate the following consumption

RPMs GPHs
0.5k 0.4
1.5k 1.0
2.5k 2.2
3.5k 3.8
4.5k 5.9
5.5k 8.5
