IIRC, most if not all 4 strokes meet the fed 2006 standards(they were after 2 stokes), in the mean time CA came out with some 2006
standards of thier own that caused the 4 stokes some trouble but most of it is "labeling", is you real want to do the 2 stoke thing
use a mercury, the work nice on the boat, nice kill switch, nice hand grip throttle/shifter and any type of prop you need.
