Dealer says mid 70's. I know the one in powerboat magazine test with 575's ran low 80's. Anyone got similar setup?

I have a 99 36 outlaw with 500EFI's and extension boxes...Top speed on speedo is 78-79...however best according to gps is 72.1

Thanks Steve,
I like your boat, saw the picture on TeamBajaMarine.com. It looked like you had the stand off boxes. How much do they help?
They tell me it will come with 28 pitch props, what are you turning?

98 36 Outlaw w/HP500 carbs, 26 Bravo's said 75 on the speedo. Im not sure of GPS speed.

I have only ran the boat with the boxes,so really don't know if they are helping my speed or not...I'm turning 23p Mirage Plus props at 5200RPM....This spring I'm going to try some different props and try switching rotation,along with several other things....

Our 1999 W/500's has seen 77.4 GPS but this was in excellent water at some point during a poker run (good chop). Typically it will run in the 72 MPH range GPS. Speedo is just a little optomistic at times, but not by much. This is a well loaded boat. TV/VCR, AC, Micro, Fride, usually full water tank etc. Turning Labbed 25 Mirage +'s at 5200 +-50 depending on load, water, weather, etc.

Steve, Nice Outlaw! Nice Pics
Quick question: Are you runing 1.36 gears in your B1 with those 23's?
...That's the only way I could make sense of your numbers?

Thanks!

Nick
While changing out drive fluid last year I noticed that one drive was marked 1.50 and the other 1.36....so i did some checking and found that they are 1.36s...In nasty water I have a hard time getting on plane with the 23s...keep blowing them out...
Steve

Hey Mark,
I guess i will have to leave my boat at home
when we do poker runs. I wont have anybody to pick me up when my boat breaks down because you will be to far ahead of me.

Thanks Steve for the info.
I know our boats are not even in the same league, but for what it's worth, I have the same problems with my 23 Mirage Plus.
