Have this exact same boat and motor combo in a 99. Bought it new that year and it still looks and runs as good as the day she came in. Boat fishes larger than it really is and handles big water very well. With the 150 dialed in right you should see top end of 61 -63 MPH provided there are no problems with your motor. I can tell you the 150 carbed motor is bullet proof. Only thing I have ever done to mine was change plugs , lower unit oil and (water pump every 2 years).
