Oh and Yamaha is the best IMHO, especially in the four stroke realm with Zuki right on their heels.
In two strokes obviously the newer ETEC's are the way to go, power to weight ratio is superb.
In older engines, two strokes, it is often viewed by many as a toss up between the major manufactures. I have had great engines from Yamaha, Evinrude, Johnson, and even an old Mariner that was a tough SOB.
I think if I had to pick from a rack of used two strokes in the same condition and price it would be a Yamaha for me followed by Johnson/Evinrude.
A lot has to do with what you are used to and knowledgable about.
