Normal Predator of that size has a draught of about 1.65m, although im not sure with the Arneson drives. Maybe someone else can give you a more accurate answer.
Predator 75. Triple ASD with MAN 1200 / 1300.... Draft @ full load averaged around 58 inches. Some sat deeper, some less deep depending on spec / gear carried etc. All had aft static trim, so the deepest draft was measured at the prop tips of the centre ASD unit, with ASD unit at neutral trim.
