I ran my 27br this weekend for the first time 500hp efi it ran 65mph on gps at 5400rpm 24bravo prop the boat has 136hours and a imco lower what prop should I try ?

id try a 24p & 25p hydro Q4. and also a labbed 26 bravo.

I think my 24b is labbed for low end it got out of the hole great with no tabs I could not trim up the motor like other boats I have owned RPMS would go up with no speed gain and very big rooster tail

24 like said above i would think would work, or call brett at bblades. he just did a prop for my mate with great results. im under reving by about 200 rpm, and he called me this morning, said send it back, he will touch it up asap and ship it back.
cant go wrong with that, and i picked up over 1 mph while still under reving!! its a 26, but he does his custome work to it, then labs it.
