The V 20 hits 50mph tops, but any faster ?

i would try a 21 Mirage plus, its probably one of the best all around props made. It doesn't work well on some of the higher strung 2 strokes, but on your 3.0L it should be fine. One of my friends is running a 19 Mirage on his 20 Grady with a 225 Yamaha 4 stroke, it runs better than all the other props we've tried. Look at the mercury "thunderbolt" its an alternative marketing brand of the Mirage, it doesn't have the deep ingaving on the side, and doesn't have the cavitation holes, but other wise(according to my prop guy), its the same blade design and surface area of the Mirage, and its much cheaper
