22p to 24p swap and losing rpm???
i have a 28ft commander deck boat and i bought it with a 22p on it and i was only pulling 57mph @ 4600rpm on a good day. Just put on a 24p this weekend and now im at 50mph @ 4100rpm. What could be the issue ?

you need to go down in pitch to increase rpm and put the prop at its most efficient rpm.... we need to know what engine you have to know what is its peak operating rpm range. the 22bravo1 is more like a 21. so a 21 3 blade would most likely act about the same. you may want to try a 19p mirage plus and mabye have it re-worked with a little more cup or pitch to about the 20 range to get you at that 48-5000 rpm range.
