So i have a 1997 20hp mec outboard motor and would like to step it up to a 25. Is this possible by simply changing the carb?

Any Mercury outboard mechanics around?

I looked into that a while back for my 1994 20 hp two stroke. If I recall corectly all it took for my motor was a main jet change on the existing carb. I debated doing it for a while and ultimately decided that the potential increrase wasn't worth the effort for how I use the rig.
