Believe small Mercury, Tohatsu, & Nissan are the same engine...all made by Tohatsu. These have the reputation of being the easiest to work on, but also the ones that need work the most.
Honda's have a reputation for being heavy for the hp they produce...but the most efficient and most reliable. But when they break down, its pricey.
I've never seen a 9.9 hp suzuki out in the world...I didn't even know they existed. A quick Google search makes me feel like the small Suzukis are rebadged Tohatsu, just like small Nissans and Mercurys.
