hmmmmm
So what's the difference between the XR and XZ drives - why would one choose one over the other?

My sense is there are a several items that can cause the variations like how they are propped, if they have extension boxes, how much load they have, what their xDim is, etc... I think it would be safe to say that a current 28 with 496 HO's should run somewhere between high 90's and low 100's.

I have xr's with 1.36, stamped on the side though i will make sure, they could be 1.35.....I am running 30P Bravos and have seen best of 93, though mine is the older tall deck boat. I am going to change the spark plugs (should be good for 300 RPM) they haven't been done in awhile and then maybe go to the 32's.... I tired them once and i was at 92 but my rpm was lacking....didn't think about the plugs till another buddy with a 496 mag ho was prop testing and couldn't get the rpms up, he hadn't changed the plugs in awhile, he did then boat gained the rpms and more mphs, plus was finally able to turn the bigger prop....
