The tail pipes were not correct, I was on a time crunch at that point ,and should have sold them ,and bought new, but ended up buying new tail pipes , so have the TRS height tail pipes for sale. I may have picked up a couple hundred RPM , but not as much as I hoped for. Overall better, and need the exhaust for future upgrades.
I have seen 73 on GPS, with a ton of people on the boat , but cannot tweek anymore out even with a light load.. Kind of wierd that it runs the same MPH heavy or light. Would love to try some other props , also spinning props in ever since I got the boat, need to try spinning out and see if any different. Love the boat more every time I run it !!!!!

I always wondered what the Brave would do with ext boxes and shorties? Mine had a pretty deep X dim, and would poirpose if allowed -- i think ext boxes with -2 shorties would free up 5 mph.
My old one is running around 76mph with 26 bravo 1's at about 5500 rpm, the engines dynoed at 600hp at 6000rpm --without looking at the dyno sheets i would assume that at 5500 theyre around the 550 mark
with the 700's/ xr's that i had in it the best i saw was 85 mph with herring 32 5 blade props -- 1.5 ratio drives
I think there was alot left in the setup on the drive end of things-- they are heavy, mine weighed in at 7200 lbs dry...
How'd the imco's work ?

If power and weight aren't changing the speed much, it could be the X dimension is too deep.
Ran into that with my 36' years ago. Raised the X 2" and it became a new boat.
