Moving that j/p up and down will get you in trouble if you don't know where it is and where it should be. Set it at a good height and leave it until you are use to the boat and what it likes. Do you have a sportmaster l/u? If you do and it is too low, it will drive like shit. A sporty should be about 1" above the pad and a torqmaster should be about 1" below the pad. A 1/2" off in height can make a big difference in how it handles.
Take it slow and it'll come.
