Prop Slip on a 36
#11
My best numbers are: 88 MPH on GPS @ 5300 RPM. Mercury Racing 575 SCi's, with labbed 32" 4 blade Bravos. I have a slightly ligher 36' with a single step. In my opinion, I don't think you will get a 36' Apache to have slip numbers lower than 16 or 17%.

Interesting, why do you drop 1 on pitch for a Bravo one prop? I could live with those slip numbers... What kind of power are you making? And is yours a full cabin?

You drop an inch because a B1 prop is variable pitch. It's not a true pitch prop like a Hydromotive QIV. Bobby will tell you that you should see similar slip numbers as mine with the flat bottom models. My boat would also be faster if I had XR's but you loose 2-3mph with the BMax. The step bottom models will have higher slip but better top end. Also, you can't gauge your slip by your mid-range, you have to run WOT.
When I ran the 92.3mph I had 875hp engines. Now the engines are 964hp and I haven't had good enough conditions to really see what she can do wit the new power. I'm expecting mid 90's.
