I just bought my first jet drive boat i havnt took it out on the water yet but planning on it this weekend i got a 77 sleekcraft executive 460 with edelbrock intake and carb it has a berkley 12 je-a jet drive on it. What mph am i looking at here just an estimate. is it easy to drive one of these can anyone throw me some pointers for me to keep in mind. the motor runs great the interier will be a project though and ill post pics as my journey begins on the interier. I love the look of these boats....
