I have a Sleekcraft 25 - Bravo 1 and BBC - 1976 that I bought last year that was complete with a 454SC and Bravo I. I started a thread over on Vintage JetBoats .com (I'm also doing a Sleekcraft SSV with a jet) to show what I was doing and what I had to work with.

I don't know too much about the internals of my motor, other that I have some receipts that Greg Shoemaker from GS marine built the motor and he said that back in the day, he built these around 600hp. I bought it and with the restrictive Indmars it came with, it could only spin a 23p 3 blade at 5000rpm for gps 60 mph. I swapped the Indmars out and went out to Elsinore on Sunday to test it out. The Mercruiser/Gil HP headers made a difference and with a 26p 4 blade, it ran 65 mph on gps at 5000 rpm.
My question to you is what kind of performance are you getting with your setup?
thanks
