Finally got my 2024 Pro Boost 155 3.25 out in the snow these past couple days. I would agree with what a lot of the peasants on here have been stating regarding the new features of the 2024. The new scratchers do seem to work a little better than the older ones. But I also agree with what others have been saying that the new track does a lot better getting snow up in the tunnel than the papier-mâché 2.75. Running my Boost down the trail next to a 23 9R with a 2.75 and the Boost was running around 105 as the 9R was 125. The new scratchers don't stay on the worthless plastic platforms. This is bad news for you sissy's who want your snowmobiles to be in pristine condition when you drive your jacked up short box Dodge through the bikini coffee stand. They will only stay put if you put them up on the aluminum rail but doin that already scratched and chipped my rails. Yesterday it was handle bar deep light snow and I must say the 3.25 does out perform the 2.75 with ease. I don't think it lays over nearly as bad but my track only has about 45ish miles on it so we will see how quickly it gets soft. I still think the 3.25 tends to trench a bit more than the 300LX but I need to ride a 300LX on a 24 Boost to be 100% sure. It definitely gets the front end of the sled up in the air better than the 2.75, which in turn makes it seem a lot more playful. The 24 bottom end is much more crisp sounding than any 22 or 23 I have ever heard. Running my 24 side by side next to 22 Boosts, you can tell their is a noticeable difference in the low end acceleration of the older boost compared to the new. I can't wait to see how it is once it's through break in because my 22 was significantly better after break in. I have about 45 miles and might be a little more than 1/4 of the way on the break in bar graph. The sled seemed to get a little better throughout the day but still leaves a massive black spot in the snow. I would say the top end remains the same. The 24 surely is a step forward but the fact is, the Boost is still a boat anchor. I does not fly out of the snow like the 9R. And even having a Skinz hood, Fox Air Shocks, and a Diamond S can on mine is still takes much more effort to ride than a 9R. However, the Boost outperforms the 9R in 3 feet of fresh. I wouldn't argue that one bit. One days where its hard to just venture off the trail like yesterday, the Boost really shines. Nothing beats track speed in chest deep snow. Though I must say I am a little disappointed as I thought the 24 would be more promising and be closer to the the Turbo R but in reality it still has a ways to go. My recommendation though if you are fat, old, not very good, and/or don't ride trees than the Boost is probably the sled you should be on.
