P5X's should out cruise the Bravo 1 props but the top end is up for debate. The debate is with the performance numbers the boat is currently producing.
Do you have actual numbers with the props you have now? If your slip is high, the P5X's should gain some speed across the board. If the slip is low, you may only see mid and low speed gains with top speed losses of 1-4 mph. We have P5X props for testing without buying if you desire.

Also, there are Bravo 1 Lab Finishing options that allow for better overall performance without sacrificing cruise.

awash, how does your boat run at 50 or so? Does it seem to run flat or bow up. I can tell when mine needs some trim b/c it seems like its running flat and dragging. A lil trim, bow comes up and it loosens up. Could help with your high slip!

I just switched my props and levers at helm and will try spinning IN to get the bow up better. If that doesn't work then I will either have to try some props or lab my 25s. As soon as i win the bblades $400 certificate it will be good!! lol

Actual numbers at the beginning of this thread and slip is pretty high. From other folks in this thread and another I'm pretty sure 27P is not the way to go. Thom helped with an option that sounds interesting. I may take you up on the P5-X to test but I want to test one more time. For me I'll take the higher cruise speed I don't run at WOT much so if I get 5100 rpm and 72 mph vs 5100 rpm and 69 mph but pick up cruise speed that makes the 5 blade interesting enough to try.

Mine needs to be trimmed up at 50 otherwise lot of hull in water I usually run between 2-3 on trim. Have never needed tabs unless I drop them a little in rough water.

I have to agree so much with Keith. Swapped my props for testing and only had to anchor close for the beach in a current and while you know they are backwards. When you need the boat to move your body forgets glad I played away from everyone haha
