Either go onto that ramp and dive, which uncovers one shortcut; or go straight, which uncovers a different shortcut.

Dolphin Park Hidden area:
In free roam mode, aim for the island in the background when you first start. Just before you hit the "out of bounds" markers, hit the turbo. If done correctly, you will see a second area. Head for that area and when you can hit the turbo a second time, do so to reach it. This may require more than one attempt. This new area has monster waves that you can do any trick on.

Lost Temple Lagoon Shortcut:
Towards the end of the track, as you are on the big turn, is a big brick wall. Run into the wall with your Jet Ski and it will break, giving you an advantage on the race. You can do this in any game mode.

Ocean City Harbor Shortcut:
After the third jump (ramp), immediately before the fourth jump make a sharp right so that you can see a red gate guarding a tunnel. Go through the gate, which opens a very nice shortcut.

Southern Island Shortcut:
After the shipwreck there is a wall to the left. In the middle of the wall is a hole. Dive to break the bars on the hole and go through it.

Strongwater Keep Shortcut:
On the second lap after the seventh or so buoy a gate will open up as you pass by. Dart into it, follow the short tunnel, then break the glass at the other end to get out.

After the large jump over the rocks, follow the right wall and find the patch of different colored wall, Break through it to reveal a tight S-curve short cut. Note: You will miss three buoys by taking this shortcut.

Free roam Buoys:
Select free roam mode and choose the Fatty and the Dolphin Park track. Go towards the mountain and you will see a ring of buoys. You may need someone fast, as it as hard to get to.
