I have the same boat and exact setup. Josh from Steves prop told me to go to 2.5" below pad. Runs perfect! Great holeshot and will get to 69 before any noticeable chine. Just twitch steering to the left to bust the chine and hold on! Every hull and prop are different. Have your prop checked, more than likely the pitch and cup for each blade are a little different coming from factory! I was told a tempest prop works the best for this boat. Don't know, I still have the factory Yamaha prop. 24p T1......
