You can still buy two stroke outboards, the evinrude ETEC.
Any other two stroke outboard you can keep, they were all pieces of crap. The newer 4 strokes are 100X more reliable.
It never ceases to amaze me the amount of nostalgia there is for junk.
Shhhh! Don't let my collection of two-strokes hear that! They have never considered doing anything except run... And very efficiently at that!
