Besides the world's most efficient engine is a 2 stroke, there's millions of 2 stroke engines running around that are incredibly more powerful per pound than 4 strokes. Anywhere from double to 4 times the hp per lb dependent on cylinder capacity.
It makes me wonder why these myths and lore about 2 strokes continue, admittedly the antiquated pieces of miserable 1960's tech 2 stroke rubbish that flyers use doesn't help, but dirtbike, snowmobile and jet ski users know better.
2 stroke's fail when compared to a 4 stroke is emissions output and space for the exhaust, but both have been turned around in recent years.
165 hp at 90 lbs, what more could you want ...

Mercury and Evinrude 2 stroke outboards not only meet Californian emissions law, they are now cleaner than many of their 4 stroke counterparts.
