Post your fuel consumption?
 

Please post your boat Make/Model/Length and Power, and how much fuel you consume at cruising speeds/top speeds and what those speeds are?

Thanks

Sonic 31ss twin 454s average 1.5 mpg

35 Cafe Racer, Slightly warmed over 502's, about 450 hp per side. At Cruise, I'm consuming 14.9 gallons per hour per side at 3500 rpms which is exactly 50 mph. So, I guess that makes it 1.67 mpg at cruise. I never took readings at WOT; I really don't want to know. :)

Don't want to know !:lolhit:

?? Is this a mis-print?

43 Black Thunder 500 efi's, XR's at cruise 3500 rpm 1 mpg

Nope. Turn-key and go!!
I've learned my lesson. Nothing beats reliability. I do damn near 200 hours a year. I want to boat, not wrench.
:cool:

What uses More fuel?????
 

What uses more fuel... A built SINGLE IO or A pair of mild bbc?

2.2 mpg with a labbed 28" Bravo 1. Just got a labbed 29" Cutting Edge prop so I'll see if the mpg goes up. Hopefully the top speed will increase. I will be doing some charting on both props to see how they compare.

.5 miles per gal 110.

My single engine hopped up 525SC/560ish hp Pantera used more fuel at cruise speeds than my 32 AT with 502mpi's. The Pantera averaged about 1.25mpg and the AT averages about 1.5mpg.

598ci N/A about 750hp

I cruise at 3500rpm and burn about 25gph and cruise at 55mph. So about 2.2mpg.

Of course the throttle doesnt stay in that position for long, and I can assure you, it gets thirsty at 6000rpm.

Good plan. For some reason I thought you had some big engines in your Cafe. I guess my memory sucks!!

What is your WFO speed?

I used to...that's where I learned my lesson. :D

WFO speed:...I want to say 70, but I'd be lying. :o
69's a fine number anyway.

25 Daytona, blown 509 / 900. Cruise at 3500 nets 75mph and 1.5mpg. 6000 nets 110 and just barely 1mpg

powerplay 25 with twin 300 xs's
cruising speed: 60 liters/hours
top speed : ???? i don't care

:D:drink::evilb: LMAO!!!!! Nice seeing you last week.


For me:
38 straight-bottom Top Gun, big cubic inch N/A's (800HP) with #6's.

I figured out last season that I average .88 mpg at cruise. 4000 rpm's is right around 60-62 depending on water conditions.

WOT.....don't want to know.:eek:


Craig

I'll throw an odd-ball in here, 32' Pachanga, 2 x 330 mercruisers/alpha, timing turned up a bit, performer intakes, stock carbs, older motors but healthy, 34 mph @ 2600 2.6 mpg WOT 63-65 at around 4700

:ernaehrung004::ernaehrung004::ernaehrung004::boat :

2mpg at 114mph

X2!!!

Hey cigdaz what props are you running? I have a cafe running 26 b 1 turning out at 3500 only seeing 46 or so thnks

2.4 Gallons per minute x 2

Lab-finished 26P Bravo 1's. You're right, when they were stock that's exactly the same I was seeing as you, 46-47 @ 3500.
My cruise speed improved substantially with the lab work.

Yikes! :eek:

Mine are lab finished,could run 28 no problem but worried about the drives,540s 5500 82.5 and hitting the rev limiter

That's good to know. I was always under the impression it usually suffered but you picked up top-end.

I didn't want to know!!!!!

About like this when on it hard.

WOW:eek: You made my day:party-smiley-004: My boat now seems liks a Prius:lolhit:

I love it!!!!!!!!:drink:

I'm with you.. maybe a little less!

1 can of red bull and a 3 finger measure of Seagrem's vodka per hour!


Once I'm moored at the dock for the night of course!

My top end didn't change much at all. I instructed that I wanted the best cruise possible, since that's where I spend 99% of my time. I doubt I have more then 10 minutes at WOT.

3800 RPM 90mph 1.45mpg
WOT ???
39 MTI 1100's

4000rpm .85 mpg

WOT 180gph so 1 gallon every 20 second....

:lolhit::lolhit::lolhit:

I have close to the same deal. I keep telling myself closer to 1 mpg :party-smiley-004: but i know your number are probably more accurate. I really rather not know. Craig, what wheels are you spinning?

AT IDLE.......
