You might want to check your engine mounting height (distance of cavitation plate from bottom of boat with motor trimmed such that plate is parallel to bottom). Standard mounting height with a bracket is to raise cav plate 1" above bottom for each 1' of setback. Don Herman set mine at 2.5" for the 30" setback of the Hermco bracket. That's just a starting point however; I was able to raise mine another 2" from there without getting significant ventilation in hard turns unless I have motor trimmed higher than about 70%. (100% is max uptrim, where it switches to tilt mode)
