I recently purchased a 1988 Z21 with a Mercruiser 7.4L with 330hp. I'm running
a Mirage stainless 14.5" 23P with a Bravo stern drive. I have been told that the max rpm is 4600 for that motor and I'm running about 4800 @ 61mph. After doing some research it looks like the Bravo I 4 blade 24P should help the top end as well as bring the rpm's down by at least 200. Is anyone running this prop or any input on Pitch/Speed/3 blade versus 4?
