You bet. With the amount of ballast I run (factory plus a lot more) with the XS550 it's about 16 gallons per hour. Just factory ballast your looking at about 12 gph. The ZR450 had pretty similar numbers. It's hard to give an apples to apples comparison though, because I run an extra 1000 pounds more ballast in the 550 than I was able to in the 450.

Another thing to consider is that the only time the boat is moving, is if there is someone riding behind it...most of the time that someone is me, and I fall A LOT, so the boat spends a lot of time accellerating from 0-24 mph. Those who are able to ride without falling too much will definitely see better gas mileage.

Those numbers are all for wakeboarding. We don't do much surfing, and have never surfed without there being a few wakeboard sets mixed in during the day.

What do you think the total weight of your G23 is with trailer and all? Like a realistic all-in weight? I tow with a GMC Yukon Denali now but I'm assuming I'd need something bigger. I've also heard the 550 HP is a must? Did you need to reprop yours?

I took mine onto the trucker scales and calculated it to be at about 8200 pounds, with a 100% full gas tank. I have about 400 pounds in gear (lead, anchors, etc.). I was towing with a Chevy 1500 Crew Cab 6.2L with Max Tow package last year (same engine as your Denali). It had plenty of power to tow it(rated for 10700 pounds), it just sucked gas down and shifted constantly. My buddy was towing his G23 with a Yukon XL, but hated the capability of the 5.3L. He just switched into a Yukon XL Denali, and is much happier.

For me, I wanted something that weighed almost as much as what I was towing, and didn't want to have it shift every 30 seconds, so I moved into a Chevy HD Duramax.

If you are running stock ballast and will have less than a total of 2000 pounds extra in your boat, the 450 is just fine. Anything more than that and you'll want to 550. HOWEVER, for 2014 they using a 2:1 tranny and 17" prop with the 450, so I'd anticipate it to perform much better than the 2013's. I reproped my 450 with the Acme 2315. With the 550, I'm just using the stock Acme 2247.

With my 6.2L I was getting 6-7 mpg towing the G. With my 2013 Duramax I'm getting between 10-12. I drive fairly fast (typically 75-79 mph), and am pretty sure if I slowed to 65-69, I think I'd probably see 12-13 mpg. Also, the engine only has 4000 miles on it and supposedly you'll start to see a little improvement in gas milage once you get to around 10k miles.

It looks like the 2014 6.2L is going to be up around 450 lb-ft of torque and will also have active fuel management. Should be a pretty slick setup.

If you put a blower on top of that you'll get another 1-2mpg...same goes for 5.7 or 6.0.

I don't think it's a better boat than MC but for me I want a surf system so I can switch sides on the fly. Only options that leaves me are Malibu or Nautique. I might look at the new SAN 230's though with NSS as I'd have to buy a new vehicle just to tow the G. I love my X25 but I don't love switching ballast all the time.

I got 40,000 miles on 2012 dmax! the mileage will suck for the first 10-15k miles. I get 10-12 towing a 9k trailer so we are not far off mileage wise. My star is around 7k on the trailer you will see ur empty mpg up some but you have to drive like a white person
