Installed a johnson hyperfoil on my checkmate starflight this past weekend. I got some top end gains and a whole lot of hole shot. Has anyone else seen the top end gains of 3-5 mph? If so, why would that be? Also could get 200-400 rpm more on top end. I can currently spin a 23 p tempest plus 6400-6500 with a 2.5 200 xri merc, thinking of going to a 26 chopper II. Is that too much prop?
