14.625 I believe is what is listed on the Mercury website

Too small? Will that even fit a bravo one? That's big.

I was on my 280 Silencer when I bought it. (Bravo 1x) Turned way too many RPM's at every speed.
The Checkmates I've owned/been on always ran best with Bravo 1 props or Mach Sterndrivers but they are hard to find. I would try a to find a 24p Bravo 1

Been looking for a bravo 1. I've been told that before. Looking for a 22p first. 24p might be to much for my setup.

I had a 350up small block the douche I bought the boat from painted the bottom I tried 6or 7 different props. Boat ran the best with a 21p rev 4 out of the hole mid range an top speed 61 on GPS ran 57with a 23 mirage 60 with a 21 laser

I have a 23p mirage plus and 22p 4 blade turbo ready for testing in the spring. Looking for a bravo 1 and probably a rev now.
