Hello my name is ***** ***** I will assist you. For the fuel consumption for the boat with these engines they are approximately the following:

At idle 4 l/hr

1000 rpm 9.4 l/hr

2500 rpm 69 l/hr

3000 rpm 98 l/hr

3500 rpm 153 l/hr

So on cruising speed you should be consuming something around 80 - 90 l/hr.

Please note that the above are approximate figures as supplied by the engine manufacturer and they will vary depending on the sea condition / load and cleanliness of boat / hull and driving style.

If you require further assitance let me know.

I replied about a week ago, but maybe my reply got lost.
Do you have any intermediate figures, or ideally a graph, please? Using the figures above, what is the most economical RPM, please?
Expert:  Noel Schembri replied 1 year ago.

Sorry but i did not get your reply, the most ideal rpm is when you get the boat on plane and you can feel the engines relaxed. The rps will be in the range of around 2800 - 3000 rpm.
