So i tryed to fix the Engine 2 centimetres higher. Now there is not that fountain any more, and SR4 runs 3 knots faster than before.
But in narrow
curves prop ventilation happens, and that was´nt before. I have´nt finished my expiriments with that. I´ll check other prop´s too. What i try to say is, if you´ll change the transom high anyway, start some higher, and expirimet the level down, if possible, and see what happens.
Nice rib you´ve got there....
