My x may have been risen not sure how to tell it has a 23 p mirage on it now but I changed motors went from maybe 450hp ish 496 to low 600 hp 540 any help would be appreciated and I was thinking a good starting point would be 28 4blade bravo I am not worried about 1 to 2 mph on top end but of course you know the story the faster the better but I do want a good all around prop and if any one has a used prop that might work hit me up I believe it is a 1.50 ratio again how do I tell for sure thanks

Call Bret at BBLADES and test a prop before buying. Takes the guess work out of it.

26-28 Bravo 1 depending on what rpm peak hp is on the 540.

24-26 b1 you don't have near enough power for a 28

5400 rpm and how do I measure my x and what is stock on this boat also how does this affect prop choice

My 240 with 615-630 hp spun a 26 to 5500 rpm with a -2 imco lower. Def run a 24 or 26 bravo 1, and a left prop will help with torque steer and lean. My boat would lay right over if I hit the throttle hard at 4000 lol

mirage always works good on bajas

Come on man! It's fun running a boat on the port side of the V... Mine did the same thing with a 28 and wasn't bad running on one side of the hull once I got used to it until the chine walk would start then it sucked.
