I ran side by side with a twin 525 38 ZR. We ran dead even. My boat tops out about 85. He did have 4 people in the boat so could no doubt have gone 87-88 alone.

I am pretty sure We hit 90mph in the 38zr Bob used to own. Raymond from Double R was driving. I do think the boat may have been running Herring Props though and we did end up throwing a blade.
