Average fuel consumption of 4JH4AE

[Vedat Midilli]

My B43 engine time is 1036 hrs at present. Because of unreliable fuel gauge, I keep a tight record of fuel consumption. What I've come at this point is 3,02 lt/hr; average of almost 4,5 yrs or 1036 engine hrs. I wanted to share this data with other 54 HP 4JH4AE users.

Thanks Vedat.  

For those that want to know the consumption in US gallons:   .80 gallons per hour or just over 3/4 of a gallon per hour, which is very close to my own experience on the same engine.   Of course the average rpm will make a difference on fuel consumption over shorter periods.

Hi Alan,

My average cruising RPM is about 2300-2400. Of course time passed in idle pulls overall average RPM down a little.

Thanks for the info.

Our B43 has just about the same number of hours with the same fuel average consumption. We are very happy with this engine. Also glad to see we are not the only ones who use our engines. Lots of sailors seem to enjoy talking about how few hours they have on their engine but it would take forever and a day to really travel without using our engine. Would be nice to buy a 8 year old boat with 100 hours on the engine but my question is "how do they do that?"

Very much my experience also. I too have logged every drop of fuel loaded on. Averaging about 0.7 gph.

I have about 200 hrs. on a 2011 Ben 40. I have the same 54 hp engine and am getting about 1 gph at 2450 rpm. If I throttle down to 2200 than I am in the .75 range of fuel consumption.

I usually run in the 2600 range (it's the sweet spot) and see 3/4 to 1 gph.

we work on 4 ltr/hr as the fuel gauge is not worth taking seriously. We also carry 40ltr in jerry cans, however, having seen Franc's second tank on CanDrac I think this is the way to go and then you always have enough safety margin for most cruises

I have a Yanmar 2GM 20 2 cly  and hold 15 gals.  Today I got fuel by the advice by a sailor who looked at my log (I feel it's best to record )  I am at 1400 hours.  Well since the last fill and w his advice I overfilled at 9 gals. He thought I must be near empty.   soooo.. I feel, I am getting good hour use...and will start checking that.  My rpm at best speed where I like it is 2600, although it is set for 3500 max.

I know this is not the same engine as yours, but thought I would share.
