I've never owned a 4 stroke anything or Yamaha, Suzuki or Honda so no insight there. I've owned 6 evinrude/johnsons (115-150), 1 tohatsu (70) and 2 mercury's (150). The mercs were garbage. I worked on them as often as I ran them. I've not had much in the way of problems with evinrude/johnson motors. No problems at all with the tohatsu. It ate props but that was the waterway I was working in, not the motor. University of Alabama research vessel Minerva on the Black Warrior River from Demopolis, AL to Franklin's Ferry, AL. About an even split between work boats and recreational craft.
