1998 Convincor 251 Prop Set up

I've got a 1998 Convincor 251 with a 454 mpi. I've been battling porpoising fairly bad the past year that I've owned the boat. I currently run a 23p Bravo 1 3 blade prop. Would a four blade help this issue? Or has anyone else experienced this and found a fix?
 
I've tried bravo, but like Hydromotive Q4-X which has less than 3 bld props. There's NO 100% fix other than running above the MPH where it porpoises. For my convincor it's about 44mph. How long have you owned it?
 
I bought the boat right around a year ago exactly. Last year, I was able to get through the porpoising and it would settle around 45 mph. But this year nothing has worked. The best thing that I've found so far is loading the cuddy with all my gear and running with the tabs up. I still experienced some bouncing, but it was a lot more controlled.
