I repowered my 1998 192 in 2004 with a F150. It was the first model year of that motor. Best money I have ever spent and when I sold the boat in 2009 it had almost 700 hours on that motor. I took care of it with annual oil changes and so forth. So, if you are thinking it being a new model or first year model, based on my experience it likely does not make a huge difference.
There are two ways at looking how to best spend tax payer dollars. You can go the cheapest route and spend more on maintenance and down time and so forth, or you can pay little more and get reliability and higher resale value down the road. Short sighted thinking has got us into this mess we are in today. I dont have an ax to grind on etecs or any other motor. Buy what you want. Prior to owning a Yammaha I was a fan of OMC products which includes Evinrude. Our family boat waaaay back in the early 1970s was a Thunderbird powered by a 85 hp Evinrude. My brothers 190 was powered by an Evinrude. I am sold on Yammaha after owning the F150 and I currently own a 25hp FS and a 250 FS.
I will say this, if you were in Florida, and you had any aspirations taking your boat to the Bahamas, Yamahas are like roaches over there and nearly every marine place I have stopped in has parts and somebody on the island who knows how to work on the Yammy. Heck I was down at Stainel Cay a few years ago in the Exumas and the one marine repair guy on the island was a yammy guy. With that said, I suspect he could tear appart any outboard, but he clearly had parts in stock for yammaha.
If anybody wants to know about a qood quality home theater reciever, the Yammaha Aventage series is awesome!!! I love mine. Honestly if Yammaha made cars I would likely buy one or if they made lawn mowers too. I drink the grey Kool aid all day long and listen to it too - lol.
