I do have a Bravo III. I think 22.4 is stamped somewhere on them but will have to see if I have any pictures of the prop to tell. I believe the props are stock from whatever came with the boat. So what's the standard that came with 2011 Sea Ray 260 Sundecks? I have a 4 bladed that's just before a 3 bladed prop. That's an option to change the pitch to control RPM perhaps. I'm surprised that the PCM doesn't just limit RPM so WOT is at or just below the limit. I'm getting near 5,000 at WOT with the trim all the way down. I give it a few shots of up trim, RPM increase a 200-300, the bow rises a smidge and I get about 3-5 MPH increase. It hadn't occurred to me that there be an issue hear but I will keep it below 5,000 from here on in based on hwat the shop tells me.
