prop help 2003 ZT230BR

Wondering why your boat would be any lighter? Not seeing how you are getting a 23p to run 67 unless you're talking speedo readings.

-Craig
GPS I have had a lot of people not believe it but it did that stock as u can see it is no longer and I was the original dealer for boat and it came from checkmate with that prop I have tried hydromotive 4 blades and didn’t have as much luck
 
It’s gos readings I had ran with many big block Baja’s similar and a big block eliminator got me by not much but I just changed hole set up
 
Does your boat have 2 steps and notched transom even my mechanic was surprised what my boat runs don’t ask me why I don’t know but it did run 67 I’m hoping with whipple 12 psi and 12 inch extension box black Hawk drive to be 88 to 90 ish but won’t be doing drive and extension till winter
