Re: Suzuki 5hp or Johnson 5hp
Evinrude and Johnson are permanently connected, and have been since the 1930s. But rather than having identical products as in the past, they have diverged so that Evinrude (North America) are all E-TEC engines and Johnson are all the Suzuki 4 strokes and carburetted 2-strokes. Since all E-TECs are presently large, you cannot buy a small Evinrude outboard in North America presently.
That division may not be present in various other places in the world. I think it would depend greatly on local markets.
