4 strokes outboards IS THIS A MYTH?

Giovanni Bracco
Giovanni Bracco
Raid 2003 GOLFO DI BARATTO/PARIS

Total Miles 2696,00
Total hours of navigation 152,00
Consumption 4680,00 ltrs
Consumption/hour 30,80 ltrs
Average Speed 17.80 knots

YAMAHA 225 4-Storkes
RIB MAR.CO 25 CABINATO

4680 LTRS / 2696 Miles = 1.735 LTRS/MILE

The reason for the low average consumption of this boat is the low average speed of 17.8 knots.
The other boats have speeds around 23 knots.

That makes a difference of 23 % !

The higher the speed the higher engine load and revolution and therefore a higher fuel consumption will be the result under normal cruising conditions.

Note:
There is no discrepancy to your interesting chart because that shows consumption defined in miles per gallon, it's the reciproke of our common European definition in l/km.
