To all those trying to inquire about this set up past or present:
That is a 12" hydraulic plate on the back with a mildly worked/cupped 26 T1. Prop to pad about 1/4" above or below depending on load and water conditions. The weather conditions are also favorable. From what I have experienced these speeds are possible with the stock slide master, but hole shot will suffer, along with mid range cruise will have horrible slippage and there will be limited turning without blowout. The best overall prop for this setup is 25T1 with appropriate work and most should see 73-75 on average with an average/moderate payload and have a low enough Prop to pad to allow a good hole shot, midrange and turning.
What I am trying to say without being a dick about it, is that people see this and expect that their boat (a new 225) will do this really easily, but that is just not the case. First off you WILL NEED a hydraulic plate to get a good setup for his boat if you want those speeds and handling. With that money invested, I would opt for a ZX250 (if Skeeter is the brand) for a grand more at this point especially is speed is the case. It will carry the load with better speeds and run a bit or equally faster.
This is just one of those "freakishly fast" boats for what it is.
