Maybe the really big big engines use fuel injection. I'm not talking about those.

There is no doubt that the 4 strokes give better fuel economy. However, on the

What's a carburator? Most new outboards use some kind of fuel
injection if they are living in the 21st century, 2 stroke or 4.
If you add the complexities of the oil injection system a new 2 stroke
is certainbly as complicated.
