    Fuel Consumption

    I was just surfing the internet about PWC fuel consumption and I came upon this web site.

    http://www.angelfire.com/oh/theboatguy/fueleconomy.html

    I know it is for SD but I was wondering if we had somthing for Polaris. I've been toying with the idea of replacing my old SLs, but when I look at SD, the fuel consumption has quadrupled from the old 587CC engines to the new 4 techs. On second thought, with gas as much as it is, I think I might just keeps the SLs, and invest in them if anything were to go wrong.

    How does a MSX 110 or the 140 compare in consumption with SLs or the 4 tech?

    I know the tops speeds have increased since the mid 1990s, and I know that speed requires thirst. But ouch! 4 times the fuel burn for a gain of 28mph! Also I read that the new Ultra burns quite a bit more than the new rxp.... meaning 5x the old crafts. That has to be heavy on the wallet!!

    The two main factors (other than how hard you ride it) in fuel consumption seem to be carbureted vs. fuel injected, and engine displacement, or horse power.

    I did read a list somewhere ranking the relative fuel 'economy' of various PWCs engine types and sizes, but it wasn't well presented.

    PWC weight and size is also a factor, the Kawasaki Ultra 250 weighs around 1,000 lbs DRY (without fuel), almost double the weight of a Polaris SL. And the Kawi fuel tank is larger than the older PWC, adding even more weight when it is filled.

    Among Polaris machines, the twin cylinder domestic engines have a reputation for low fuel consumption, and I think that applies to both the carbureted and Ficht fuel injected models. I would expect the Ficht twin to do a little better, fuel wise.

    I don't know how the other Polaris models would rank in terms of fuel thirst. So far, I have been happy with the fuel burn of my 1200 Polaris injected machines.

    The fuel burn on my MSX 150 is, in my opinion, very frugal. I usually burn from 8 to 10 gallons on a hard day of riding...a great deal of that time at WOT. I have never had to end a day early, because I was running low on fuel.

    I attribute the fuel economy to the fact that the engine is turbo charged...and I am getting 150 horses out of only two cylinders.

    So a MSX 150 is much better than a GTX's 12 GPH at WOT?

    Does anyone here have the fuel consumption specs for the various Polaris models?

    The tank on my MSX 150 holds 18 gallons, and the engine is only 750cc. If I was using 12 GPH, I would be off the water in under 2 hours! Even though I don't know the actual GPH for the MSX, I can assure you that it is considerably less than that....

    Smile 785 mileage/gph

    seems like i saw 12 gph at wot in a manual on our pro 785's. with less than 10 gal tank dont take long to run low plus theres no reserve. actually carry a 1 gal biltz can of premix in storage compartment (just fits). so kinda thirsty but sure is fun and cant put a price on that!

    just found where i got info: polaris service publication 2000 slh, virage,pro 785. had to do the math to get milage.
    here the info:
    pro 785 range 40 mi, tank 9.8 gal=4.08 mpg
    slh range 50 mi, tank 12.5 gal=4 mpg
    virage range 61 mi, tank 17 gal=3.58 mpg
    note all are based on full throdle cruise.

    Is the range spec based on running the fuel tank dry, or just until the low fuel warning appears?

    According to the odometer on my twin 700cc Virage, I get approximately 6 miles per gallon on average. That is mostly WOT.
