Hydro Thunder

Arctic Circle Shortcut
Look for a hole in the ice on the right side of the track about one-third of the way through. Hydro jump into it and you will go careening down a long tube. This should gain you several places. You will exit FAST, so be careful--there are some turns just head and you should not miss the boost fuel in them. There is another boost further down on the left side you can hydro jump to get and cut the corner short.
Towards the end of the race, you will see a hole in the ice to your right and a large ship just beyond that on the left. Drive toward the middle of the ship, crossing the ice bank, and you will receive a secret boost. You will also enter the second shortcut. Try to exit the medium right turn on the outside because there is a long, flat ramp that will rocket you ahead a place or two right at the finish line.

Get Hard Crafts
Get to the screen where you pick your craft. Press ALL THREE views at the SAME TIME and the hard category will be activated. This makes it easier to get the two cheat crafts with the pilot code, and to get the hard crafts without having to go through all the normal trouble to get them.

Hidden Track: The Nile Adventure
Activate the code to race at Hydro Speedway. If you earn a free game at this track, a new track will be available to select on your new game, the Nile Adventure. Be careful though, this race is VERY difficult.

Hydro Speedway Track
To race on the Hydro Speedway Track, highlight "Lake Powell" at the track selection screen, then quickly press the PILOT button three times.
When the track splits in two, steer toward the grassy spot in between the waterways of the next split. Use your boosters to travel down this grassy spot.
Jump the very last ramp of the track and hit (yes, HIT) the Start/Finish marquee on the right side about where the words "to go" appear in "laps to go". You will flip through the air and receive a 9 second boost.

Lake Powell Secrets
On the Lake Powell track there are 3 secrets. First in the waterfall, go through it. Second is, when you round the corner where the teepees are jump over the decking to find a secret tunnel. And third when you get to the bridge with the two 4 sec. boosts, go up the incline that is in the middle. You can get the 9 sec boosts by doing so.

Lost Island Shortcut
The first shortcut is behind the first waterfall. Go through this waterfall for a nine and a four second boost. Immediately thereafter, you will see some huts off to the left. Drive (DO NOT JUMP!) between the last hut and the rock just beyond it to access the second shortcut and grab those two boosts that are just too high to get. The hidden boost in this track is in the volcano flames--you must jump the ramp to get it.

Solo Racing
At the boat select screen before you select your boat hold down the low view and pilot buttons and pull the stick in reverse then you will be the only one racing on the track.

Super Start
Before the race begins, keep the throttle in the STOP position. As the "3" begins to fade, throttle to full. As the "2" begins to fade, throttle to stop, and when the "1" begins to fade, throttle to full again. You will get a turbo start as well as a +4 second boost of fuel.

Tournament Mode
At the boat select screen, before you choose your vehicle, hold the HIGH & LOW view buttons and bring the throttle to Reverse. You'll hear a chime to confirm. This code disables the game's "catch-up" feature. The code will also work in two player mode, but only if both players enter it.

Waterfall Waterway
In almost every level there is a waterfall. Don't be afraid to go in it, you won't crash. When you go into the waterfall there will be a secret tunnel that you can go through. Not only is it faster, you also get a lot of boosts along the way.
