To the best of my knowledge, the four strokes are difficult to get the power up, to many parts and pieces and expense! The older two strokes were pretty simple, usually just a carb change.

Simple and 2 parts.
Remove 9.9 restrictor plate and install 20hp flame arrestor. Gives you about 15hp.

To get 20hp, replace 9.9 ECU with 20hp ECU, of same year and motor type.

Now you've learned something.

I think suzuki is the only motor this can be done too though.
