The key to mastering Hydro Thunder is learning to use Hydro Jumps effectively. To perform one of these jumps, pull the Throttle into the Reverse position, then press the Boost button while holding the Throttle in Reverse. You must have Boost fuel in order to perform a Hydro Jump, and the amount of time you hold down the Boost button determines how high you will go. Hydro Jumps are effective for clearing obstacles, grabbing boosts, and reaching certain shortcuts.

At the Choose Track screen, highlight the Lake Powell track and quickly press the Pilot button three times.

To start a race with a burst of speed, hold the Throttle in the neutral position between Full and Back during the countdown. When the number ''1'' starts to disappear, quickly move the Throttle into the Forward position.

Enter this code at the boat selection screen. You must enter it before you select your boat. Hold the Low + Pilot view buttons and pull the throttle to the Reverse position until you hear a confirmation chime.
