I'm currently running a labbed (Darin/HP) 24P 3-blade and am going to go with Raylar's BCK103 kit and the CMI headers for the 496 Mag HO.

We're at about 6000' elevation and I'm currently running about 69MPH GPS at 4900 RPM. The boat is an H2X so it's very light. I know it won't be perfect, but I really want to get the prop in the ballpark before summer. Any thoughts would be appreciated.

Thanks!
Steve

I would probably start with a 27p mirage plus.

I agree with Bajarunner, unless you want a little better handeling and midrange, then I would say Mecury Labbed 26 Bravo
