25 Thunder, HP500, (with APBA Factory 1 seals), 81.7 mph. Thinking I was right at 5150-5200 rpm.
Also tried a standoff box for a short time. Played with a number of drive height / prop type /pitch-dia. combos. Andy (cig-3?) and/orBrad, (Funhome) may remember better but I think we were just touching 83.0-83.1 in perfect chop with the box. Problem was we had so much bow lift it was not a good rough water setup. As the saying goes; It's not how fast you go, but HOW you go Fast !!!

BTW, Most of our testing was with a lab finish 28p Bravo 4-blade. We also played with a cut down 30p Bravo 4-blade, a couple of 26ish <wink> Hydromotive 4blds and a (very) trick/custom Spenilli <sp?> 4 blade.
