Gents,
May I ask for your advice
background: I'm having an AQD40 / SP280 in my 26 foot boat
The max RPM is 3550 / 23 knots
I wonder if my fuel consumption is within specs?
At 2800 / 13,5knots the fuel consumption is about 22ltrs / 5,8 US gallons
At 3000 / 15 knots the fuel consumption is about 30 ltrs / 7,9 US gallons
I feel in my case the consumption at 3000rpm is a bit high as I read from somewhere that the max consumption for this engine should be somewhere at 36 liters / 9,6 US gallons per hour at max power 3500-3600 RPM. As such I'm not far from that at 3000rpm?
Now If I understand correctly many run this engine at 3200-3300 cruise rpm? Also, VOLVO states that 3300RPM cruise speed is fine.
Based on your experiences I wonder what the cruise consumption at 3000-3300 range should be?
I do think maybe I need to have a look on the turbo / injectors as I think they nave never been rebuilt. The engine has somewhat 800 hours on it and has good compression.
thanks in advance,
Artto
