As said above, do you really want to press your luck? Prop seems to be working for you...

Call Todd at hydromotive, he can find you more ( Not sure how much ) , your near the end your boat looks to be dialed based on the speed and where i have been with mine . I would start saving your money that Xr Upper is gonna BLOW up trust me , been there done that. As you start labbing the prop the blades will weaken , you might want to have a spare. Hydromotive 5 blades are the best on velocitys , i have tried max/bravos 4 blades etc. always end up back with a 5 blade hydro .

I don't have an xr, but would love to try a 5 blade hydro. I'm just worried about breaking the b1 drive. With 800+ hp I'm already asking a lot from it with a 32 bravo 1. Not to mention I've busted it twice cruising with a combined time of 20 minutes total. Lol
Hopefully the new thick gears will help with from blowing the bottoms out. I'm sure long enough to find the next weak link. Lol

I have a 2002 VR1 race hull, 638" BBC one carb, no blower, Bone stock 27" Hydro P5. My XR was good in design up to 95 mph however like they said its only a matter of time before it blows with more then 600hp. Last season I bolted on a Imco std length1.36 lower and ran 101 MPH the first step on the pedal but a hose broke so that was all the testing I did, I just finished bolting on a new SCX upper with a 2" shorty SC lower and am testing it today. That is the best drive package for any 90+ mph single vee hull as long as you have the right length lower, The prop of choice is the P5, What I would do is buy a second one, Send it to Todd at Hydromotive with all the info he needs to tweak it, Then switch them to see which is best. Good luck
