Can anyone help with gas mileage for a 350hp V8 5.7liter Merc Cruiser? Is there anything anyone would know about this year, make or model?
Thanks,
Mark

Fuel economy will suck. If you got 3mpg, you'd be doing good.

What I know about a 2335 of that vintage is that it's a big 23' boat. More like 23'8" long. The only one I ever road in, was a 97 and it had the 7.4. And that's the motor I would want. If the one you are looking at is a 300hp 5.7, that's good, but if it's a carbureted 250hp, I don't think you're gonna like the performance out of the hole. If it's a 5.7LX EFI Gen +, it's 280hp and it would be okay, but no rocket. My boat (1997 2135) is a short 21' (20'6") and has the 5.7LX EFI Gen + with a Bravo 3 drive, and it doesn't go 60mph. And I get around 3.5 to 4mpg if I am real careful.

Hope that helps.

I have a 1995 2335 Chapparal 5.7 23.8 feet Don't know about MPG depends on tide, wind etc.

Normally 5-6 gallons a hour. Running Bravo 1 brand new engine 4 barrel
Great boat! Rips out of the water WOT about 4500 rpm.

Although I think I am going to with a little more prop. I have been avoiding the change over from Alum to Stainless for awhile but its time with the new engine.

Problem with stainless is trashing your outdrive if you hit something and electrolysis increases alot.
