What pitch prop are you running and what power? I'm repowering my 87 220 and need a baseline prop. I have never had this boat in the water.

I have a 23pitch 3 blade prop with a stock 454 330hp. The boat has been converted to a bravo drive with 1.5 ratio.
The original alpha drive was a 1.36 ratio and had a 22pitch 3 blade. Both setups run around 4700 rpm. Low 60's with bravo drive, mid 60's with alpha. (never checked with GPS).
