    24P Fury 3 with 3 L plugs (actually they were solid but I drilled them out to match the L size in my other props)... 12" hyd jp (plus poles and agms). Hole shot is pretty strong with the L plugs, no reason to remove them completely on my rig.

    About 5800-5900 rpm... fastest I've seen was 76.5

    About 5800 76 MPH. I really need to adjust my throttle I think to get 6k, but it’s plenty for me so I haven’t done it. Manual Z Lock plate that came with boat.
