    What should my max RPM be?

    09 FX SHO, freeflow exhaust and Riva intake kit. Topping out at 63mph. Just wondering what my RPMs should be? Maybe I won't wait until the 100 hr oil change to switch plugs.....

    on the stock prop with your upgrades your rpm must be around 7500 to 7600

    in fair weather you should be on the rev limiter the moment you install an air intake 7750rpm but only way to accurately tell is to invest in a tiny tach.

    I should be on the water in a couple hours. I'll see what rpm I'm getting.

    Pulling 7300-7400. I think I'll change the plugs and see.
