I found the 5 blades made a difference on top end with Imco -2". Your 4 blade Bravos are probably good for your application if they are in the correct rpm range. Not sure where you should be propped with your power? Might want to have Bblades take a look at them.

Well we winterized the boat last weekend so no more numbers atleast until spring. But yea, I'll probably be shipping the current props to Brett @ bblades and see what he thinks about the condition of them. And when it gets closer to spring I'll probably take part in his test program he offers. But in the end, I'm thinking labbed 4b bravo 32s or 34s will be the best until I get shorter lowers on the boat. And then with shorties, 6b or the new 7b herings will probably produce the best speeds. I atleast want to have new props on the boat for the loto shootout next year!
