Well, while the comparison between a Yamaha and an Evinrude may be under the Ford vs. Chevy Debate, the Evinrude compared to the Chrysler would be classified as a Chevy vs. Yugo debate. See where I am getting at here?
They have notorious design flaws, and a nonexistent parts base. They are just known for being the king of unreliability.
Now may be a good time for this comment. Yes, I am indeed Johnson/Evinrude guy. Partly because when I first got into outboards, I was in need of something cheap and reliable to fish with. When I was first looking at outboards, I soon came to the conclusion that the Johnson/Evinrudes are the most reliable even from decades back, and the easiest to work on/best design, and longest continuation of the same part on motors even decades apart, all while staying at the top of the modern technology for the time.
Thus, when I kept buying more and more outboards, I just kept with the brands I was most familiar with, and still consider them the best, as none other have motors dating back so far that are still considered reliable enough to use as a main motor.
The foreign brands (Yamaha, Honda, Suziki, Nissan, Tohatsu) all make fine motors. But, they are generally more costly, and don't date back so far, so they aren't at the top of my list.
The Mercury/Mariners, way back when, were awful. Not known for reliability, and incredibly hard to fix (but they were incredibly fast). Water pump impeller replacement on many of them involved taking off the powerhead. The real new ones I personally would avoid, as I would with any boat made by Brunswick, due my feeling that they don't pay enough attention to quality control these days, and there smaller motors are a bit behind on technology. There isn't much wrong with the mid age (think 80s) mercs, but I tend to just avoid them all.
The Chrysler/Force motors were badly designed, and have few reproduction parts, so getting parts is real tough. They are not exactly known for reliability.
Now, all of these comments, aside from the one about Brunswick, are for motors 15 years old or more, as that is mostly what I deal with. Only time will tell how well the new motors really are, and we haven't had enough time to tell for most.
