If I remember correctly, up to 40-50hp, Mercury's are rebadged tohatsu's.
Two years ago I called local dealers about a new 25hp. One is a Mercury dealer, he asked me if I cared about who's sticker is on it. I said no. He said get the tohatsu, and save some money. Said you can take any part you want off one, put it on the other.
Around here, if you see a Suzuki for sale, it's usually not for sale long. Especially the smaller ones.
