They are certainly torque monsters and definitely pull well above their weight in the bottom 2/3 of the throttle range where you spend most time. I've been super happy with mine (2019 135HO, V-6) and have had no trouble. A 200 etec, could easily sub for a 250 Yamaha or Suzuki based on peak torque. I know that a bunch of the etecs from the early 2000s were lemons (just after BRP acquired Evinrude and the etec design was still in its first generation), but BRP sorted the design over the years and I always thought these final ones were reasonably well regarded.
Evinrude just pulled distribution of their outboards in North America, but these motors are still available in the rest of the world and access to parts has not been an issue and warranties are still valid.
The main issue is that these use a lot of different tech versus a conventional 4-stroke. Mainly its the direct injection technology which is basically unique to Evinrude - so injector problems can be expensive, versus replacing an injector on a conventional fuel injection system. Likewise, you have a secondary oiling system. I think the main problem is that you need familiarity with a different set of issues from a conventional modern 4-stroke, so repairs can seem daunting and unfamiliar. If you've had one before, or have a local mechanic familiar with etecs you are golden.
When I bought my boat, the etec definitely didn't increase the selling price, and my gut take at the time was that it was a liability. Now, I'm glad to have it, and it punches way above the number on the cowl - I will try to get my 1000-1500hrs out of it.
