Gonna pin me down on that, hu?
OK, sure. Why not? Seriously, once you get over 60 stuff comes under you pretty fast. Add to that the wind ripping tears from your eyes.....it really isn't safe, or smart, and the more company you have out there the less smart it becomes.
I don't care how good of a boat driver you think you are, I work on these things for a living and I absolutely HATE when someone comes in wanting me to troubleshoot a glitch that only happens at 6000+ RPM because that means eventually I will probably have to go test run it. Not real fun for ME, and I've logged more hours behind the wheel of a boat than anyone on this board.
