Ian,
I have never tried pulling a skier with my boat, although that being said im sure it would do it. Just no interest.
Im running a 28 TE Cleaver, engine height is adjustable, propshaft was almost level with the bottom of the boat for the 98 run. 6" of Setback.
I would predict 65 - 70 mph range, assuming the motor etc are up to scratch, and the engine height etc was spot on. You said 2" lift, wheres the propshaft in relation to the bottom of the boat? Do you have low water pickup gearbox? This allows much greater engine height and in turn more speed.
Get a low water pickup box, cleaver prop, and wind that moor right up... Then she will start moving.
Let me know if your after a gearbox, i have a cle for sale.
