VOLVO 5.7 8cyl carburizing 235cv consumption incredible?

wrote:
It depends how fast you run it, figure about 4 l/h for every 10 actual
horsepower. Typical fuel burn for that engine would be in the range of
40 to 60 l/h.

Hello,
I am about to buy Chris Craft 260 Crown with a VOLVO PENTA 8 cyl, 5.7l,
235hp 1997
Some says to me that that it consumes 35l/h and others 60l/h even more.
Who can tell me the truth.
Changing the engine for a MPI necessary?
Thank you for your information

As Wayne says the harder you push it the more fuel it will use per hour.

I would tend to disagree on his 4 ltrs/h for ever 10HP & the engines
fuel use "range" will exceed 60 ltrs/h.

A more accurate measure is to just divide the HP being made by 3 & call
it ltrs. So @ 235Hp it could be using as much as 78 ltrs/h but at the
normal cruise for a boat like that (around 2/3 max revs & 1/2 throttle)
you will find 40 ltrs/h is about right.

Sustained running over about that cruise setting will not only burn lots
more fuel, it will also shorten engine service life.

Changing an existing engine to MPI from carb(s) would not be justified
on the small fuel savings made, even at today's prices:-)
