I honestly couldn't tell you and have no experience with a 192 Tournament, that being said I'd first start off by posting this in the General Discussion part of the forum as you'll likely get many more answers. Just from what I've gathered and seen over the years, the Evinrude motors have been discontinued since I believe 2020, so I'd factor that into the equation with regards to pricing and parts availability in the future if you needed anything. I know that a buddy of mine has twin Etec's on his Wooldridge and next to nobody wants to work on them, even though I guess Mercury Marine is supposed to. I also know that the Etec motors, depending on the year, can have a few issues with them. I personally have never been a fan of 2 stroke motors, even the Etec's as they're louder and smell compared to the 4 strokes. If you're looking for alternative weight saving options, I'd maybe consider a 140 hp Suzuki as they only weigh 410 lbs, which is considerably less than the Etec and much closer to the weight of your current motor. Good luck!
