Kenst du die schraube "Signature BS1" 15 1/8" x 26 ?
@ Frankscarab; I've some problems with your numbers / prop pitch..
I've run your speed numbers through our slip calculator; assuming you have 1.5 drive ratio, spinning a 25P @ 5100 RPM = 75,6 MPH on GPS ?? giving a unrealistic 6 % prop slip
Only 6% prop slip is very unlikely for that (old style, non stepped and V not cat) hull... a 3 blade prop... specially is really labfinished...
Our 28 ft Heats with 496 HO (without CMI's) are all running 24P (or 26P labfinished) most of the time, hitting the rev limiter... 496 HO with CMI's turned this year 26P and / or 28 P labfinished. Same prop (28 P labfinished) for Checkmate with 500 EFI (28 ft boats while yours is 22 ft)
I always repeat, it's really hard to calculate / advise if you don't have correct numbers to begin with / or if you don't know exactly who did the labfinishing or repitching.
I also know the Signature BS1" 15 1/8" x 26 prop which has to be considered as a low performance (low cost) prop..copy from a copy from a copy... perfect to use as a spare prop but NO way a high performance prop.
It's hard to follow your thoughts...You have all the best and very expensive stuff like a 496 HO and the best CMI headers and now trying to save a few hunderd euro's on a prop ?? 496 HO with decent prop will run faster / better then 496 HO with CMI's and "bad" prop....
Cleaver props might give you the ultimate topspeed but too much inconvenients for daily use (poor acceleration / poor midrange / prop blow out etc.
Basing on your numbers, I would start testing with a 26P 4 blade and depending on those test results deciding to go with the 26P or 28 labfinished
We have those props in stock & please feel free to recontact us for our prop test program
