Would regularly run 92-93 Seen a best of 96 @ 5850. Also had labbed throttle up 6 blade 30p props. They were always faster than my herings. I also removed the cabin interior. that made a big difference in ride and handling.

That's impressive with 525's. Do you know where your prop shaft height to hull depth is at?

Isn't the IMCO lower faster than the sportmaster?
