How can I make my Tracker 40 HP faster?

I had a spark plug problem trick me into a new injector a few years ago. The plug would spark in free air while grounded to the engine case but would not spark in a chamber with 5 psi applied to it. I found it was bad by pulling plug wires one at a time with the engine running and confirmed it with a cleaner/tester set.

That is why a lot of us Ask if the Spark will jump a 3/8" or 7/16" Gap. Air is an Insulator, and the Denser it is, the better of an Insulator it is, and the Voltage required to Jump the Gap increases.
