Just found out about these forums recently, and your post has convinced me to register.
My question however is how did you get that boat to run stable at 103.5mph! (that is what you meant?) I have a 25' Convincor, which I'm assuming as the same as yours, or close. The hull is not stepped and I keep getting told I'd max out in the 80's. Running 90+ would be great, how did you do it?
