For a petrol boat 8M v hull with twin 150 HP z drive Volvo Petrol engines what fuel consumption should I expect?
if anyone can give me a rough idea it would be appreciated.
I am looking for a boat and the one I have found is this spec.
Thanks
 
I would have thought 6gph at a mid engine rev cruise per engine.

It owul held to know the weight of the boat and the age as this will influence things as well.

Engines use exponetially more fuel at or near top revs, so to keep things efficient(ish) aim to keep the revs under 75%. i.e. if the boat revs out at 4,000 rpm, try to cruise at 3,000 rpm or less.
 
Have twin 135hp Mercruisers which if the volvos are AQ151's will be roughly the same as they put out 140hp
Mine will use 14-16GPH flat out and at a cruise of around 22 kts use about 9 GPH. in a Sealine 255. On the river at 6mph on 1 engine it is just under a gallon an hour.
