Lets hope not, you won't get the same thrust out of a little four stroke that you get out of a two stroke.
Unless you are going over 30hp you want the acceleration of the two stroke and they ain't the noisy old smokers they used to be. Remember a four stroke is much heavier that a two stroke so if you want a smaller boat to scoot along you want a two stroke.
It wasn't long ago i went through the same exercise.
Seems counter productive in this day and age to influence people to get bigger, heavier and more expensive motors.
IMHO
