Search this board for this topic. I have provided feedback on several different threads.My best was 74.7 GPS with a 27″ Trophy, standard jackplate, Puma DC with 225 Pro XS. Second best was 74.0 GPS even with a 26″ Tempest.The 25″-26″ Trophies are good, all-around props year-round, and will serve you well regardless of conditions or load.If you have a manual plate, set engine height approximately 3.25 below pad. If you get it too high, the hull wont lift.Good luck, and email if you want.Gary Hollander
