I have a champion 203 with an OX66 225. Looking to get more power out of the motor. Based on the research I've done Heads are best bang for buck, followed by Reeds.

I'm debating PH2 or PH3 kits, Whats the expected HP difference between the two? Looks like the biggest difference is the throttle body? Any real world fishing gains from the lightweight flywheel?

At what RPM does the OX66 stop making power with the PH kits? I know you can cut the rev limiter, and TBH I don't feel comfortable spinning it all the way up to 6700RPM, however I'd be happy to prop it to turn 6300-6400RPM.

And lastly, I've read alot about low pressure fuel pumps having issues after a PH kit. What is everyone's go to external fuel pump they are using, and where does one find a clean delete kit?


I know it's alot, but I have alot of questions.
