Water Damage/Airboat Level
If you're stuck at a ramp that's going in the opposite direction of where you need to jump, go under water and look under the ramp. You'll see a basket type thing with a blue barrel in it. You need to grab two more blue barrels where the sewage tubes are. Grab them and put them under the basket. You'll see the ramp start to float upward. Once it does, jump your airboat over it.
If you find yourself stuck at a point where there is a large closed dam gate to the left and two wrecked boats to the right, TURN AROUND. YOU'RE GOING THE WRONG WAY!
You'll need to backtrack 2-3 load screens until you reach a red barn-like building. There, you'll find an elevator. Park the airboat on it and take it down.
