Speed/Fuel Comparison between my 189 and my 2011

Got a chance to really run my 2011 for the first time since I got it good and broken in. This is the first time since I picked the boat up that I have fished by myself. I thought people considering a 189 versus a 2011 may enjoy seeing the speed and fuel differences:

189 with Yamaha F150
RPM Speed GPH MPG
3500 29.9 5.1 5.86
4000 34 6.4 5.31
4500 39 8.3 4.70
5000 42.9 10.3 4.17
5800 50.3 16.6 3.03

2011 with Yamaha SHO 250 Four Stroke
RPM Speed GPH MPG
3500 37.3 8.1 4.60
4000 43.3 11.3 3.83
4500 48.8 15.2 3.21
5000 55.5 19.2 2.89
5900 66.2 22.8 2.90

I found it interesting that my MPG was the same at 5000 as it was wide open. I may as well open it up if I'm running above 5000 RPMs. It makes me wonder if the GPH reading is right at wide open, but when I refilled my total gallons was pretty close to spot on. These comparisons were both done in fresh water, I suspect I will see higher speeds in the salt.

    What prop are you running and do you have a jack plate? I have no jackplate and am running a bravo 1FS 24 pitch on mine and can only turn 5500 or 5600 without losing too much bite.

    I do have a jack plate and was running it up 2.5 inches. I also have a Bravo 24. At Max RPM, I had it almost to the top of the trim Guage with no slippage. I'm wondering if the 6 inch set back of the Jack plate may make a difference.

    Last weekend I launched in the dark and had raised the Jack plate all the way up while it was on the trailer and forgot to put it back down. I was pretty amazed that I ran around half the morning with it all the way up and never noticed it. I was trimming it some too. I wasn't running super fast that morning but it still amazed me that I didn't even notice it.

    One thing I forgot to mention is these are both Carbon Kevlar hulled boats. My old 189 had a poling platform and my new 2011 does not. I also went with all lithium batteries in the 2011 so that is a substantial weight savings as well over AGM batteries (about 180 pounds). Both boats when I speed tested them were pretty new, around 15 hours, both were loaded for fishing (I tend to be a real gear hog), both boats have dual power poles, and I am pretty heavy then and now(about 260).
