i had the 14.25 X 14 OJ on my 05 mcx xstar. it was absolutely out of this world. i believe it had the 110 cup. it was the smoothest, most linear prop i have experienced. the allowed the perfect pass to really lock in solidly. the boat could stand about 3500-4000 lbs ballast total. it would take about 25 seconds to get up to cruising speed but it could do it. that prop is as good as it gets for a heavily loaded mcx engine. however, i strongly suggest e-mailing eric at johnson propeller (oj props) and telling him all of the variables that will be involved in your application. also, the cup will make a difference, ask him what cup he would recommend. good luck and let us know what he tells you. do whatever he suggests. he has never steered me wrong and i have had 7-8 different oj props on my three mastercrafts, '99 205 V with LTR (330 hp), '05 xstar with mcx and '08 xstar with L18 (14.75 X 15.5, wow).
