Alan, When first firing the motor and let it idle what happens is that in 2 strokes, the motor starts to load up the fuel system which is caused by the base compression creating back pressure, no matter Carbs or Fuel Injection. Also you are exhausting through the Prop which is close to the surface ... Sometimes you even see Puff Bubbles reaching the surface like a cig smoker blowing rings. ... But like you said after you get out of stagnate water and have some current and the exhaust is not trapped it isn't that noticeable.

Now to be honest some manufacturers of certain outboards smoke more than others by design ... depending on how the combustion chamber is designed ... Example is it a looper or a crossfire, or other design. ... <'TK><
