Default 36 Daytona Open Bow slip question

I have a the 36' Daytona open bow version with 500EFI's and have a question concerning slip and speed. Presently, the boat is equipped with 1.5 Bravo XR's turning 32 pitch Bravo one props and runs 88 top speed with a slip ratio around 17%. I am considering purchasing a set of SC600's and wonder how much speed I will gain. I realize most speed calculators put it at around 95 MPH, but I was wondering if the slip will drop with speeds over 90 since the boat porposes a bit in the 80's. I am thinking once it gets moving above 90, maybe the hull can start working, packing air, and lower the slip percentage, thus making the boat his the 100 MPH mark. Thanks...

This may not be a good comparison but have 30' Daytona bowrider. I do not know if the props spinning at lower speed causes the extra slip. Got 36" bravo 1 props, and 1.36 gears. I may be off on the speeds by a little but not too far off. 3000 rpm = 57+ , 24 % slip 4000 rpms = 95, 5% slip

I am going to say with right setup you should be around 107

Try a set of labbed 5 blade maximus props. Need diffuser removed or reduced. Higher rake is your friend. A cleaver style will increase your hop. Yes your boat will be better mannered if you can get past the speed your at now. Now my opinion skip the 600's and have someone who knows what there doing redo your 500's with some 3.3 whipples. Will be much happier this way. Then you can start breaking drives...
