Did the motor lock up from lifter breaking? What caused the prop shaft splines to twist?

The Bravo was crap for me, but I was running a labbed 32". Best I've seen is 88 on GPS with stock setup and running a Hydromotive P5 30". Boat would normally run around 86 with stock setup, but 88 with very little fuel and some chop. Recently bought a set of Maximus 30", with a little larger diameter than the P5. The P5 is a really nice overall prop for the 33ZX, comes up on plane nice and easy, good cruise speed and good top speed. The Maximus is a little tougher to get up on plane, but cruises about 3-5 mph faster and will probably have a better top end, but I'm having an issue with the too much stern lift (it appears) which makes the bow start to rise and fall rapidly once in the upper 80's. I will have BBlades lab my Maximus props to help eliminate this.

In my experience this big boat loves a 5 blade. It appears the trick with speed on this boat is getting the right balance of transom lift and prop bite.

To note, my boat is a ZX Daytona with 575sci's and ITS.

The note: changes everything. 500 efi heavy hull 33zx and runs 76 topped out. Can't complain but still room to improve. I'll try the 5 blade should opportunity arise.
