Fuel Consumption for Volvo Penta MD2020

[Railbob]

I've just bought a Jeanneau Sun Odyssey 29.2 which has a Volvo Penta MD2020, what I'd like to know is its average fuel consumption per hour,could anyway hazard a guess ?

A pretty reliable estimate is 1L per hour per 10hp. This doesn't work at the extremes - we use proportionally more when using all 75hp and when only using 10 of the 75hp but the average for normal use is about right.

 

[Tranona]

Around 1.5l hour at cruising revs (2400 approx), maybe a bit less. This assumes that your boat is correctly propped to achieve maximum speed at near full revs (3600).

Flat chat, 3,000 revs around 3l/hr, which is why we all go slowly. I'd agree with the 1.5l/hr at around 2,200/2,400 but could not be precise.

Sun Odyssey 32 with MD2020D, I average 1.5lph using 2300rpm giving 5kts.

 

[Cantata]

Moody S31 with MD2020B, overall I allow for 1.3L per hour, this includes harbour work and all. Seems to usually be about right.

Thanks to everyone, your figures will give me a rough range using engine power only. As I said only just starting out again after a big break away from sailing and I'm absolutely raring to go ( once I get my V.H.F., day skipper etc)

2.3 L /hour at 2300 RPM, from memory,giving about 6.3kts on a 31 ft boat
2.0 L/hour at 2000 RPM giving circa 5.9 kts ditto
Brunton Auto prop
Bit better with fixed volvo prop

I reckon he may have worked out the fuel consumption for himself during the past ten years.

OOpps!
I picked it up when I was looking for something else & did not notice the date.
