180° Nose Stab
This is one of the greatest looking tricks there is. It starts out looking like a jump into a table top, but ends up 6 feet under and making bubbles! First find your launch source, then get a good hit off it. Mid air, crack that sucker over and pull hard down on the bars. If you have it right you will end up pointing straight down, and with the bottom of your boat facing the direction of travel. Nail the gas just as you enter to make sure you have full penetration then pull out when it's finished.

180°Tailstand Jammin along pretty fast (above plane speed) crank the bars 1 directon, lean way forward and rock the ski up onto it's flat surface so you are sliding on the belly. As you get around 180°, hit the throttle to stop the ski once you've slowed down enough. I use the weight of my body to pull down and sink the back of the ski deep, this will naturally put you into a tailstand. 

Bunny Hop
Get going about 20 mph or so then nose in and hop hard with your legs. your PWC should dive down a foot or so then spring back up and jump a little. Practice your timing and soon enough you should be able to clear the entire ski out of the water with minimal effort. Make this more of a timing issue than a force thing, it'll help a lot. This maneuver is an excellent emergency thing, so learn it well, you never know when you are going to come across something you'd just rather not hit, and are going to fast to avoid, To really get your bunny hops good I'd suggest buying a small beach ball and playing with it a bit. Get to where you can easily clear the ball with each pass.

Fountain
Yet another huge crowd pleaser! The fountain is maybe the most request trick after barrel rolls, but much easier to do if you have the right equipment. Make sure you don't try this trick without adequate bilge systems or a scupper valve. Get the ski going at plane speed and get into your bulldog position, crank the bars over and do a 180. While in motion, spin yourself around on your hood so you end up facing backwards, belly on pole, hands on grips, and feet dangeling off front of boat. Let the craft begin to slow, as the nose starts to go under, give it about half throttle. You should blast a huge fountain out of your pump. Try this trick in the direction of sunlight for rainbow fountains!

Bulldog 180 sub
A fun trick to practice and master, the Bulldog more than anything shows how much a rider really has control of his/her ski as a "platform". Get going plane speed, kneel down in the bucket and reach up with your left hand to your handhold or whatever you use to hold on. Turn your right hand around so that you are using your thumb to manage the throttle (practice until it's comfortable, you use it often). Goose it and get your self a good launching boot then crank the bars hard left squeezing a bit more throttle to break the back end loose. As you slide into a 180, let off the gas and begin to balanace and control your ski as the nose falls into the low spot towards the end of the 180. Feather the throttle up as you regain control and build plane speed again to complete the trick.

Backwards Riding
I find it easiest to practice this at first on your knees. It allows you to have a much lower center of gravity which will help a lot when riding backwards. You will have a tendency to want to tip  over because your natural reactions make you turn the wrong direction. Practice is the key here, nothing will make it feel comfortable except just getting used to it. Don't forget to look forward from time to time to make sure you have a good clear area.

Tailspin
Go as slow as you can, lean way back, crank the bars and hit the throttle. A good way to practice this is to start slow doing doughnuts. Practice doing them smaller and smaller until you can get it to circle on 1 point. When you've got it down you should be making a big V with your body and ski. Your body weight should be pulling against the torque of the engine so that you and the ski both hold a solid 45 degree angle to the water. When you are ready to exit the spin, just lean forward and move 1 foot up in the bucket.

Submerging (Subs!)
The main deal here is to get the whole ski to dive down into the water and completely submerge. I find that the calmer the water is, the better chance I have of getting the perfect pre-launch and it's a lot easier to get down with practice. Get going just barley plane speed, try to pre-bounce the ski once before you do your big pre-launch jump that gives you the lift to do this trick. Mid air in your jump push your shoulders forward while keeping your arms extended and duck a lil... The first few times you will have a tendency to slap the front of the ski down, but just keep trying, you will get it then it's like riding a bike. Remember, flat water is best, don't go too fast, and ALWAYS make sure you have a working bilge and plenty of water depth. I've actually got my ski to go backwards once I dove it in, so play around with throttle and posture

Tailstand
The object here is to get the bottom of your PWC as perfectly straight up and down as possible while still maintaining control. Go as slow as you can, stand with both feet in the back of the bucket, lean back and let the back end sink a couple feet. Pull up and get the front end high out of the water. Balance and control are the two keys here, the jet constantly wants to unload, while the ski itself wants to go down. When you are doing this right you should be more than half way under water yourself so practice someplace warm. I thought I was doing them fine for a long time until someone pointed out that the top of my ski was vert, but the bottom still had 30 degrees to go. The trick ended up being to take my back foot and put it behind me for better control. To end the Tailstand, just pull yourself closer to your ski while leaning forward. If you have a handhold, this trick is a great opening to the Corkscrew which will then set you in perfect position to ride it out into a Bulldog.

Power 360°
The Power 360° is a good basic trick to learn, it will take some time tho. First get going about 15-20 mph (just out of the water) then raise your pole way up and lean forward. Do a 15° turn to the right to set yourself up, then crank it hard left. try to sink the nose just enough so it catches and pulls the front around. As you start to get the nose under, nail the gas and let the ski pull itself around. By the time the ski gets straight again, you should be going the original direction, a complete 360 :) a common problem is breaking the pump free of the water and sliding on the belly of the craft instead of carving it into the water.

Barrel roll
This trick takes tons of preparation and practice, but once you get it there's no better crowd pleaser to a freestyler. Some people use "L's". Practice a few times until you get a good sharp wake lip made each time you try. Roll to the left myself (goof foot) so I enter the wake lip heading from right to left, with a slight right-hand arc. Pound the gas as you hit the face and crank the bars to the left hard, as the ski begins to roll up the face you should be starting to throw your shoulders left and pull left on the handle pole. If you nail it just right, the ski should rotate up around you counter clockwise. Too little gas and you end up entering the water upside-down (face-plant), too little shoulder action and you end up eating major shit!!!
