17' Z519 225 pro xs 24P fury prop (no plugs.) full tank of gas both live wells full and loaded down with all my gear. No passenger with me It started chine walking very bad around 66MPH got worse as i sped up to 70mph not able to drive it out for sure. Motor was trimmed a tad over 3/4 up. I didnt even look at my RPM's it was so bad i just let out and forgot to look at rpm gauge I had just finished 1st hr on break in cycle and had to hurry up and leave. My P2P is 2 3/4" which was set from factory. I checked it last night. Wish I had thought to glance at my gauge, but If my RPMs are in spec at WOT should I be looking into lowering my motor or raising it to stop chine walking. And should I experiment with adding prop plugs?
