My specs are accurate with dyno sheets from Derryberry racing which they installed the motor and performed the tests with as well. boat was with two full size adults and nearly full tank of gas.
540 cubic inch Merilin
1050 dominator
Custom made twin wall tuned headers
MSD limiter set at 5800 rpm
629 horsepower at 5600 rpm
Bravo one xd
bravo one 4 blade 22p gave on gps 67.8 mph at 5800 limit
52 mph at 4200 rpm and 60 mph at 5050 rpm
bravo one 4 blade stock 24p on loan yielded exactly 70.0 mph
at 5450 rpm
next was a 28p and the boat and engine could not pull it
My last to try is going to be a labed bravo one 26p and I hope to pull 72-73 mph at about 5300 rpm.
If anyone has a different suggestion or idea please inform me as any input is of value to me.
does anyone know what it takes to put a portapotty in a 28?
Oh by the way the boat is run at lake texoma in Texas and all tests were in weather between 65 and 75 degrees in April 2007

Mine came with a porta and it was in the front center compartment, you couldnt use it in there ya had to pull it out to use it.
If the 4 blade stock 24p on loan yielded exactly 70.0 mph
at 5450 rpm. I would think a labed to 23 would get ya back up to 5600.
