RPM Air Gap is my vote.

I ran a similar setup. AFR190R's. XM276HR. 1.6 rockers. RPM AirGap.

I would say the Performer for that RPM range. I could be wrong.

With that engine it was a 23p Mercury TRS 3blade cleaver labbed by Hydromotive. Spun 5500-5700rpms. Your setup should peak 5200 + rpm. What exhaust?

Right now Iíll be running stock with y pipes next season Iíll probably put in the through transom exhaust
Will be doing the work in the next couple weeks to get everything put together but right now itís a stock 350 mag with the upgraded cam and Iím spinning a 14 19 @50mph @5000rpm 21sr br advantage with 6 girls and 2 ice chest full of beer
just trying to pick up my cruising speed more thatís why Iím doing upgrades right now It 30mph @3000 with the 14 19 offshore prop but it blows out at full throttle so I have to watch that 21 bravo one Itís a little too big still
