Are 496s the most efficient motors frequently in sport boats? What kind of mileage do folks get with them in single and twin applications?

Curious because I just ran 400mi this weekend at 1.6-1.84mpg.

1350s running race fuel. Avg 11 mpg at 173 mph in 21 ft bayliner. Slightly better mpg figures if runnung twins in it

I get about 2.5 mpg in my checkmate 270 with 496. Cruise around 3700-3800rpm. Some top end bursts here and there.

Hull efficiency, engine efficiency and water conditions play a major factor in MPG.

I get totally different mpg in 0-1 footers vs 2-4's.

All joking aside, my friend gets 2mpg in his 42x Cigarette with 1100's and that's cruising at 75/80 with a few hits of 100+. (and it accelerates like a rocket)

The new turbo motors are scary both in their performance and efficiency.

Wow that's great. I wonder if top gun unlimiteds are getting similar with OBs.

Don't think I have ever seen a Cig Top Gun with OB's? Are talking about the 39 Top FISH?

Typo I meant top gun open. Did I get it right that time?

Ah nooo... Top phish

Whos turbo 1100 tommys at chief?
It takes an azzload of gas and hp to spin a big blower...
But its almost worth the extra fuel to have blower surge at the docks... Blower surge makes Hot skanks in tiny bikinis all kinds a wet...
