I'd agree with BigWavs. I've had my 24 for 9 years. I've had motors in it that would run high 60's to low 70's as well as the stocker that would run high 50's. I've never, not once, experienced any chine walking. But you do need good tabs, a good prop (they seem to like 4 blades better than 3 blades in my experience), and tight steering (hydraulic recomended). Fever Mike, if the Baja you drove chine walked at 65 mph it was NOT set up very well. My boat with the current power will run 64 most days and is ROCK SOLID at that speed.
