That’s bad ass just got me a 96 xp just got it running good replaced all fuel lines and cleaned carbs. Like how u listed all mods. If I get a impeller like your would that be the best mod? (Love the roost)
Do u have a different nozzle also? I want all around performance not neccisarly top end. How do I get that roost too?
@kansasbondboat77
Well to get roost like that you need to shorten the VTS arm so that the nozzle can go as high as possible. I also have a 3 degree pump wedge that really gets the jet pump higher. It is a lot of fun soaking people. lol

Best setup for these boats hands down is the Solas XO prop which is a 16.5/24 pitch impeller and a set of R&D 85/88mm exit nozzles. Easy RPM gain and 1.5 to 2mph up top. I have them but was testing the taller pitch X1 prop 1st which is 17/24.
