I have a 2004 Yamaha 8hp "high thrust". The prop is only 3 blade but it's big for a kicker. I've never had a single problem with it. I don't know if they make a model like it now but it's a nice motor.
When the day comes I have to replace it, I'd take a look at Yamaha again but I'd also take a look at evinrude two strokes. Ive had those on boats here and AK over the years, they were great motors. Supposedly the new ones are better.

Hondas are nice but I couldn't justify the extra cost given the success I've had with Yamaha and Evinrude. Warranty wise, I've always had the belief that the longer the warranty- the more likely you're going to have problems.
