I had Procharged 500's in a V-hull. That 50gph isn't far off. Insurance for non-cat experienced driver will cost more than the fuel you burn all year.

My 31 Cig Bullet burns 40 GPH w/ 575 HP each. My boat is for sale and could be a great boat for you!!!!

Thanks for the replies. Right now I'm just doing some research for a possible "project".
The owner of the boat pm'd me with some info.

LMAO!!

I just filled up last night.....and did calculations that I probably shouldn't have.

I went 136 miles (95% of this was 3600-4000rpm's) in a 38 Cigarette with 800's
I burned 171 gallons

That is .8 mpg...or 1.25 gallons per mile

70 gallons of AvGas @ $4.70 per=$330
101 gallons of 93 octane @ $3.279 per= $330

So, that's $660 to go 136 miles for a grand total per mile of .....................$4.85 per mile.

Like everyone else has said, the gas isn't the expensive part.....breaking chit is and everything breaks eventually.........if you use it

My 382 was probably the slowest and nearly the only powerboat boat out there Saturday afternoon. Sea's were 3's an occasional 5. I trimmed 3 down backed off to 30 MPH and had a fairly soft ride. My Granddaughter was asleep in the back seat so I wasn't going to get crazy but I couldn't help but wonder what the ride would have been like at 50 - 60. One of you guys must know.

P.S. I am the slowest guy on the highway too.

My apologies I meant the above to be a new topic

What does that translate into GPH? Roughly

I agree with all the comments about gas being the cheapest part of owning a HP boat. Every year something unexpected breaks and usually has big costs associated with the repair.
I can't imagine what your insurance will cost
Unless you have a lot of cash to burn do yourself a favor and start out with something to learn on first. JMO

I run a 382 with 500 EFI's and burn slightly better than 1 gallon per mile at 3800 rpm's.
Good Luck with your project.
