That seems very quick and unstable for only 23 feet in the water.

When Ive hit my top speed it had some chine walk but triming down just a hair really helped that, I could run at 68 no problem at all. I wouldnt say it fell really unstable, you just have to practoce how to drive it .I have dual ram trim tabs on mine, but at WOT I dont think they are even close to in the water unless full down. Im really hopeing the 3 blade will have less stern lift and will keep it in the water better. Sping time will tell, if it ever gets here.

More power means you can go faster without full trim, less trim means more stable. Or thats how mine feels
