Trying to help a buddy out. 2021 FXR 21 Limited. Atlas hydro jack plate. Yamaha sho T2 prop and twin 8 foot blades. He is having speed issues. 1 person tourney load. 69.5 mph. Rpms 5900-6000 depending on jakeplate height.We think the boat should run 72-73 realistic. I have heard the T2 need some work. What are you guys running jackplate at and what prop works the best. Any help appreciated.
