Sorry didn't follow what you're saying KK32, other than what you said about fuel prices, I just hope they're still here when I get to start boating again. It's appeared to me that the biggest difference in MPG between the X's and XS's was in the mid range but once you open them up they both burn if I remember correctly like 34 for the XS and 38 GPH for the X's which isn't that far off. Do those numbers sound right to others? If so maybe the X's really are the preferable motor if they make more power at a reasonable increase in fuel burn. Unless you've got three like some of us 
LOL
DR, I'm also closely following you on this one, I went from twin xs on teh last boat to trip X's on the 32 Skater, I didn't get much time on the Skater last year before the season ended but am loking forward to this coming season. I'm in teh process of going through all three motors and redoing the dash and a bunch of the rigging, anything I should look out for? Also curious is you had any issues with getting the X's working with the vessel views? I ask becasue I'm planning an all glass dash but using a gateway to two Garmin units, at least that's the plan for now...

Regarding fuel mileage it is still early and I will have more concrete data soon. I did however measure the fuel used in the tanks with my dipstick and it matched what the computer said was used. Average was 1.7mpg. Keep in mind that this for the day. Based on distance covered mileage wise I am inclined to say for the speeds we were going fuel usage was about 20-25% more while in break in.

Keep good notes Ron. Others (like maybe me) may need the info on how to make the X's communicate with vessel view. My boat came with two uninstalled Smart craft "gauges" that will install in place of the tachs. Not sold on the looks just yet.
Just wonder if anyone has tried an ipad for a glass dash GPS/plotter. Seems to me like it would be ideal for the application with a 4g/lte modem. Inland and coastal of course. Anyone tried it?

Absolutely correct. Used one in my airplane and could angle it to see a little better in the sun. Airplane is a low wing with a big clear canopy so lots of light. When it overheats forget about it, just blacks out saying it's to hot. Always at the worst time also!

There's no way those X motors are only burning slightly more fuel than the XSs. I've owned 28s w/ 2.5s, 3.0s and 3.2s and can guarantee you that the 3.2s burn 60-70% of what the 2.5s and 3.0s do (6k cruise w/ 2.5s, 5k cruise w/ 3.0s/3.2s). My roundtrip runs out to SF and back to my house are just over 200 miles and the 2.5s and 3.0s wouldn't make it on a set of full tanks (very close though). I do the same run with my 3.2s and I have around 50 gallons left when I get home. I do agree that at WOT, they don't get a lot better mileage than the 2.5s/3.0s, but at cruise up to 5k or so, they do WAY better on fuel. There's no doubt that they'll never truly match the performance of the 300X motors, but they definitely are the most economical way to go decently fast that I've found. Please hurry up and get those X motors broke in/dialed in so we can see some real world #s on the difference between the two motors! I'm still amazed you went through all this trouble Ron, but I'm also really looking forward to your results! Good luck with it!

I don't have hard numbers on 300X vs 300Xs but I'm amazed at how long fuel last with the 300XS. When I took the 28' to LOTO for the weekend I was always refueling. With the 308 larger tanks and 300 XSs we covered same runs and never refueled.

I agree with you guys that the xs is more fuel efficient. I will eventually have enough data to come to my conclusion. I too have made long runs for a day and know how much fuel I used. Will be doing much of the same with these motors too.
Dale it was more for fun than anything else. I like a challange and wanted to do something different. Just like your 15" xs motors. I look forward to the results as well. Just need to find time to go boating. Unlike you guys that live on a lake or river the weather down here does not always cooperate and couple that with owning a business it equals no time for boating LOL!!!
