    Tempest A45 prop OK to run on Optimax Pro XS

    I am currently running a 25 pitch Tempest plus on this 2016 Pro XS 200 motor and getting rated RPMs at WOT . I have an older A45 Tempest prop for a spare .
    I had heard the older A40 Tempest prop was a bad match for an Optimax due to the hotter exhaust gasses breaking down the pressed in rubber hub material on those props . The A45 Tempest has the flo-torq hub but the blades are supposedly thinner than the newer Tempest Plus props .
    Anybody know if the A45's thinner blades can handle the additional torque of the produced by a 3 liter Optimax without excessive flex or bending out ?

    The prop should be fine. I ran an A45 on my Ranger for years. The concern with the thinner blades comes into play on the go fast boats where you are surfacing the prop.
