So I have an 04 Champion 206 with a Yamaha 250 OX66. I just put a 10" Atlas Hydraulic jackplate on it and put a 25p Tempest that has been balanced and blueprinted. The boat jumps up on plane and rides really good on the primary pad. Top speed 63.4 by myself-gps on the lowrance at 51-5200 rpms,and that's all it will turn . I know the motor will turn way more-5900-6000. What gives? Do I need to go to a 24? The motor has new plugs and compression 150 each cylinder.
