I have a 2015 Nitro Z9 twin 12 ft Tallons 10 inch manual jack plate 250 Mercury Opti Max pro xs. PTP height 3 1/2. I have tried a 24 fury best speed 65 but alot of rpm left. Tried a 25 t1 and a 26 tempest. Good hole shot. But top speed only 60 into the current out of the 26 tempest.This with full of fuel one person live well empty. This is nothing like my old Triton from what I am reading. What PTP height and prop Is best? I know someone has been thru this. Thinking should to be able to get 70 out of it atleast Because I know if I can get my top speed up I will have a good cruising speed around 50 at 4500 rpm. Instead of 35mph. With this hull design I don't know how much. I know full of fuel going out I will gain Rpm and speed as the tank gets lighter at the end of the day. The 24 fury # are half tank one person. Empty live well.
