Surprised no one has responded to your post. I searched long and hard at jet ski options last year and after a detailed comparison of many makes/models of what I wanted, I went with two 2020 GTI SE 170's. I'm old, and don't need to go 70+ MPH on anything, but wanted something powerful enough and playful enough, that even the adult kids and grandkids could enjoy. I specifically did not want anything with a Turbo, as the cost/benefit and maintenance of a Turbo unit is something I really wanted to avoid for my use and the extra 10MPH from a turbo just didn't justify additional cost/maintenance expense. I get 57MPH top end on the 170. Just cruising the lake, which is the majority of use, is fuel efficient and pleasant. I can go an entire weekend on the 16 Gals of gas in the tank, depending on how hard I run. I also wanted a closed-cooling system, even though I will likely only use these in fresh lake water. The 170 has proven to be a good pick for my purposes. Most bang for the buck. I'm glad I went with the 170, because it has more than enough balls and power when wanted/needed in the normal or sport mode, but can be tamed for others less experienced or with bigger balls than brains through the use of a "Learning Key" or Eco Mode, which my adult kids have affectionally called the "Beoch Key or Mode". The hull is extremely stable, yet the ski is nimble and responsive. The lake I primarily use (Lake Anna in Virginia) can be choppy at times from lots of boat traffic, and this ski handles it well thanks to the VTS and stable hull. Just trim it out based on water conditions. No regrets at all spending a little additional money for the 170 over the 130, and not having to spend a couple grand more on a turbo'd PWC.
