15% slip on your run.

My bravo one drive with a 26p labbed cutting edge 4 blade gets 12% at wot and 21-25 at Econ cruise.

I would think labbing yours could cut the slip down and get some faster numbers.

Back in the day they would cut them off on the open class race boats to gain some mph.

I understand slip. You asked 'What kind of slip will good on these 3 blade cleavers'....

I do not know what is 'good'?

As stated in previous post - 5400 rpm.

Good Luck!

Yes, I was joking about the shallow water!
There was a engine package offered back in the day, the K-600, that came with the skeg removed. That must have been thrilling to run without some type of rudder.
