    14/20 prop question

    ok my cousin has a 14/20 solas concord waiting to be used but he seems to think he doesent have the power to push it.
    he has a 2001 gpr1200 heres his list of current mods
    he has d plate with sensor
    free flow
    power penum filter
    choke plates removed accel pumps removed
    carbs are jetted and bored
    reed stuffers
    r d grate and plate
    primer kit
    13/19 solas maxed out at 68-69 half tank gps

    he has riva rec heads to be installed and a tiny tach to be installed and wave eater clips.

    if all this is installed and running rite
    that is enough to move a 14 20 rite?
