Currently running a stock B1 22p on a 23ft stingray (roughly 3500lbs). Turning a B1 with 1.50 gears about 5850. 434 made 533hp at that said level. Motor setup now makes 618hp and is setup to turn to 6300-6400. I have pretty much accepted the fact that i need to start from scratch on a nee prop setup but what do you or anyone suggest? The boat originally had a 23p rev4 on it and was absolutely pathetic. Bad porpoising and no speed. The B1 helped. Seemed to lift bow as well as stearn slightly but even with the B1 i feel like i can point the nose to the sky and it wont really get the boat loose enough (lifting stearn) like it needs to be. What do you or anyone suggest? Boat does not chine walk and is very planted. But i am also trying to prop it to spin 6200-6300 to be somewhat safe.

Sorry for the delay in response. It has been rather busy around here lately.
A couple things come to mind.
First, we have propped numerous Stingray's with Rev 4 props with good success. We have Labbed most of them to get the best results but stock castings have also done well. In most cases the Rev 4 will have more trim reaction than the B!'s
Next, I'm surprised a little that you are not turning the 22 B1 a little higher in the R's with 615 HP. That being said, what speed are you seeing at 5850 rpm?
Have either of these props been worked or repaired?

Brett i have since spoken to Brad. I am turning 5850 @ about 71-73 GPS when it was the old setup (533 hp) New setup just came off dyno and made 618hp. looking for fastest topend and cruise speed. I don't pull anyone on a tube or ski's and not fast cornering. The B1 just feels as though it still doesn't get the stern up out of the water enough to get it loose feeling. Does not chine walk. The Rev 4 bogged bad and had a bad porpoise to it over the slightest trim. Did not like the Rev4 at all. B1 was night and day better and a little faster. I will be water testing saturday with old prop (stock 22P B1) to see where i land. Was looking at what the affects of a labbed Hydromotive quad 4 would do over a labbed B1? Looking to spin motor to 6200-6300.

The Q4 definitely creates more stern lift. The down side to that is the Q4 has less bow carrying capacity.

With the B1 currently i can stick the nose sky high if i want. It feels like the boat certainly has the power to lift the bow via trim at will?

Let me know how the 22 B1's ran and the performance numbers. Potentially we can work with the propeller you already own.
Or we can use our test program to test a variety of propellers from a variety of manufacturers. No other propeller company offers a program like this or the modifications and Lab Finishing we can offer.

Sounds to me like you need a shorter drive. How far below the bottom is the center of your prop shaft?

You have likely reached the limits of your hull's design. You CANNOT just continue to add HP to a boat and expect it to continue to perform linearly. You would likely be much better off taking your 618HP and putting it in a 29' Fountain, 29' Lavey or something else with a higher caliber of marine architect design, as well as at race proven speeds.

Our hull hits a wall at 74 and it'll start to get squirrelly. A little driving through it and it is good up to the upper 80s, though I don't know if I want to go that fast in it. That was from the great DocRoc who is no longer with us. Also a shorty isn't needed till mid 80s. I had one at 72 and all it did was make more problems. We should talk and share some trials and failure in our quest for speed in this hull.
