Hate to sound unpatriotic, but the Japanese 4 strokes will probably give you the best reliability and fuel economy, much like in cars. I have had both Honda and Suzuki outboards over the past two boats. Current motor is a 140 hp Suzuki 4 stroke and has honestly been just about bullet proof. Even quieter than the Honda I had before. Lots of serious trollers use the Hondas still. The Yamahas are good too. Pull the covers off of each before you buy. I was happy with the components I saw on the Suzukis (Mikuni, Hitachi, etc). I plan to seriously look at the Suzukis again when I repower. I think Suzi even has a 4 cylinder 200 hp 4 stroke now if that says anything about their R&D. The Suzi may even be a little cheaper than the other two. Good luck with your search.
