Skools, Ferm, any other JohnnyRude gurus;
On the 3 cylinder 50/60/70 hp motors, they are all essentially the same. Right? What are the differences that make up the horsepower variables? Is it all carbs? Are the reeds different? I'm almost sure that the bore and stroke are the same on these motors, but could be wrong. I really don't know.
Please enlighten me.
