"My 5 week old motor with about 30 hours on it will rev out to 5400-5500rpm 41mph at first, but after 1 hour of driving, tubing, watersking, it will only rev to 5000-5100rpm 35mph. I ve brought it back to dealer they cant do nothing for me. Looking for any advice."

Seems over propped perhaps. You neet to get to 6000+RPM. Keep driving until the motor breaks in. Maybe it will loosen up. If there is somthing wrong with a new engine the fuel is the most likely culprit.
