So what is the right prop then?
The one I've got in the works has a 28 pitch 4 blade on it that I believe the dealer just "threw on". |

U would need to run it and see where your at !!! RPM and Speed wise !!!
Then go from there. I just spoke with the the dealer and there's a 26 pitch on there now rather than the 28. |

That's why I'm sceptical.
What's the weight of your AT? What's the weight of PP with a single? The PP is quite a bit lighter I believe, as it is slightly "less tall" (less freeboard) and pretty light on the ameneties. I do think the PP is faster than the AT with similar power from what I can gather.:party-smiley-004: |

Yes, but if someone else has something similar that would at least get me in the ball park.

I think mine weighs about 4800 lbs. The 28 PP is still a pretty big boat from what I can tell. A 29 Fountain(really 26 feet with a step) wont run 80 with a 500 EFI. I cant see how a straightbottom true 28 foot PP can...

Labbed 26P on my AT with 525 spins to 5200...right where it should be.
I'd think the AT to be a "fairly similar boat" (biggish 28, 24 degree straightbottom), so I think the 26p should be a good start for this summer then and I can fine tune as I go. Thanks.:drink: |

Oh,,and i take bets on that .........so lets hear a # if u don't believe me !!!:eek: Also the At has a lower X then the PP and the angle of the transom is 2 deg. less and on and on. Its like comparing a Cig. with an Apache,,,,they are similar but not the same at all. |

Yeah, I'd love to see 80 but that's the math I was doing as well. The 29 stepped fountains I think can see 76 with a HP500, but might be a bit heavier. If I can break 75 I'll be surprised/pleased (this is with a standard Bravo 1).

I dont even think the F1 29 Fountains ran over 90. My brother has a 29 Fountain with a 525 that has been rebuilt to over 600 HP. It runs low 80's. So, I do not believe you, but I am not a betting man either:drink:
