I am not an outboard mechanic, I am an automotive hobbyist.
But, the way it has always been explained to me:
Small engines typically have "tuned" airboxes which provide a certain amount of restriction at certain points in the RPM range. The engine may run lean or rich without the factory designed airbox, with a loss of power and possible engine damage.
I would recommend replacing the airbox.
