I have swapped from a 24p tempest to a 25p and was wondering if there is a general rule of thumb for which way to move the jackplate to try and get more gains out of the top end. With the 24p I was hitting 65mph at 5600 rpm and with the 25p I hit 68mph and still had 5600 rpms(on vessel view). its a 200hp pro xs opti on a 10 inch manual jp, 18'8" cobra. Would like to see 70mph. prop to pad is roughly 3 3/8, driveway isn't super flat or level.
