32's vs 34's Handling...not good!!
I added a power upgrade to 525'2 and Imco lowers (std length)
I ran 32 pitch bravos up to 89 MPH and was close to the limiter. Handling was very stable and good at 89 MPH.
I ran 34 Bravos this past weekend and anything over 84 MPH was a handful. They are very stock and pretty thick blades. I think they were raising the transom too much and causing serious chine walking, almost uncontrollable. Great cruise at 80 and 4400 RPM though. But start to push over 84 and it was BAD. I think I can spin them to 5200 RPM, but not the way the boat was handling.
Should I get the 34's labbed and cleaned up or look for a different style prop?

Probably because the leading edge is 1/4" thick!
Its not that thick, but these are terrible!
I have a friends 32P with a cup from BBlades. I'll try them next. Just dont think the picth is enough to keep me off the limiter.

May try switching the props to turn them in, you can do it for test drive by putting it in reverse and driving it just to see. Our 388 did the same thing when we had 5 blades. Just a thought.

Thats what Joe suggested, but the issue isnt the speed. I think the 34's are just in need of thinning and cleaning up. The 32's are stock too and the boat handled perfect up to 90.
I will try turning in too. Anything might help.
