Jason Kunkel told me there is more in the tank. The lake was rough with a very strong cross wind so he believes there are another 2 MPH to go.

Mid 80's was my goal and the goal is reality now!

Ok I have scheduled the sea trial and pick up of my ProCharged Stiletto on Monday, 23-May.
Kunkel's has been fantastic to work with. Jason explained to me today that he typically does not do sea trials in a case like mine, 454 MAG MPI with stock ECU. He says the boat will start and run just like it did before the ProCharger.
Can't wait to see the performance numbers I get after some serious seat time.

We will do the Sea Trial ourselves only because I am 5.5 hours away, just in case.

Default Need some advice

Okay picked up the Boat and she runs as advertised, she screams! But I am very worried I continue to bounce off of the rev limiter even with a 30P Bravo 1. Mercury Racing recommended a 32P Bravo 1 FS but JASON Kunkel is concerned the boat will lose the incredible acceleration she has. She pulls like crazy all the way to 80MPH.
Do I purchase the new prop (calculation is 88 MPH) and give up the awesome acceleration?

Jason likes to prop boats like that. When we picked my Dad's boat up he had a 25p Mirage Plus on it and he was right, it pulled like crazy through the mid range, but would be all over the limiter. So I came across a good deal on a 27p Mirage Plus and threw it on. It did take away some of the mid range grunt, but we picked up about 3-5mph and it still touches the limiter from time to time. So we have kept the 27 on the boat. Good thing is, I think that 25p Mirage Plus is going to work nicely on my boat!!! But I would say you should at least try to track one down to try. Get one for a good price, that way if it doesn't work you shouldn't have any problem getting your money back out of it.

Corey,
If you are interested I have a 25P & 27P Mirage for sale. The 25P got me to 69.9 MPH GPS with the stock engine. The Mirage prop with identical pitch will turn 200-300 higher RPM's then the Mirage Plus. I picked up 4 MPH going from a 24P Bravo 1 5150 RPM to 69.9 MPH 4900 RPM 25P Mirage. The Mirage trim range was so much lower with the natural bow lift in the Mirage.
I also tried a 27P Mirage Plus 66 MPH 4400 RPM.
My 27P Mirage has never been wet or on a boat. I say this because if you can turn the 25P Mirage Plus you can turn the 27P Mirage at about the same RPM & my slip #'s with the Mirage were @ 10%.
If you want to try it just let me know.

Does the 27 have a removable hub and if so how much. I'm running a 26 Bravo right now and believe there's more. I need the removable hub option due to my 1-1/4" prop shaft.

I might have to get with you on the 25. I'm thinking the 25 Mirage+ might be a little to much for my boat since I will be spinning it up to 6500, and I will need all the bow lift I can get with losing all the weight out of the transom with the LS motor. I'm actually thinking a 24p P5x might be in my future.
