The Merc is 20GPH more efficient at cruise speeds!

Something doesn't sound right about those numbers does it?
52GPH at 3500rpm seems high but 65.7GPH at 4000 rpm? .9MPG vs Mercs 1.37mpg? Just doesn't sound right.
What is it, a 625 hp NA motor or a 1500hp sterling?

They are not my numbers. They are taken right from the article. So at a steady 50 MPH the Merc will go 611 miles and the Ilmor will go 360 miles on 430 gallons in the Outerlimits 39 Quattro.

Does Ilmor have service centers set up around the USA? I know there are none in Tampa.

does this mean everyone should take there mercs to the local Chevrolet dealer ????????

I owned a Hustler Slingshot with V10s and Arnesons. Great engines!
I sold it to a customer and just bought the next with the same setup.
I will not buy a Mercury anymore in my live.

I would love to know if these GPH figures are right or not? Like I said already I am a fan of the Ilmors but if the figures are correct its a big turn off I wish someone with some facts would let us all know

I only drove the boat for a very short time, but my customer uses it quite much and is happy about the fuel consumption.
I cannot understand where these figures come from.
