Hydro Jump:
     To  do  the  Hydro  Jump you must have some boost power. To do it
brake  and then really fast do your booster then the boat will jump up
into the air!

9 second boost:
     At  the start of the race, between countdown from 3 to 2 rev your
boat  up about halfway, then let go to let it go back down. When it is
all the way back right at 1 rev it up again and hold it until the race
starts.  If you did it you will start with a nine second boost. It may
take some practice, but it works for all boats.
