Superjet Porpoise with video link

Hey man, i really think you should NOT do any mods to your ski and just ride and practice. You look good for 4 hours. How you use your throttle is everything.

Think this will be my path for a while. Need some hood straps though - Had an accident this weekend and got really lucky she didn't sink all the way, haha.

You bounce after fast turns. When you are going from turn to strait you have to "recover". At the end of the turn go against the grain of the wave and dig dig dig in. If that makes sense. that will make you connect with water as soon as possible. You have NO CONTROL when there isn't water in your pump, so you have to be conscious of what you're trying to do.

A the point you bounce you have speed and right before you are in the air your pump pushes enough water for you to jump above it. Make that speed "stick" to the water by keeping the pump in it and you can set yourself on a wave for a huge jump thingy

I put my girlfriend on my superjet and it was porpoising like crazy... stopped her and told her to scoot forward more in the tray more when riding fast... problem solved.

Other than that, ride ride ride.
But you should weigh the ski and see how much it is.. maybe the rear of your ski is water logged and has too much extra weight at the back of the ski.. that could definitely contribute to the problem

I move forward and was pushing into the bars and mine would still do it. If the machine was waterlogged it would show when it was at rest in the water?

When I first got my superjet, I had been riding JS550's for years and years ... I couldnt get the hang of the superjet and almost sold it... it felt like riding on a knife blade and porpoising more than I was used to.

After a summer on the superjet, Its easy as pie. It just takes time mainly... (unless your ski is water logged)

Well I sold this ski and bought a 2003 that is bone stock. Will post up video when I get the hang of it. Going riding tomorrow!

You could also shim the back two bolts of the ride plate, which in turn will push the nose down. Worth a shot, if the forward tray stance isn't helping.

I made some progress with mine a couple days ago. If I would put my right foot to the front of the tray then slightly turn left the porpoise would stop. It was like switch I was always trying to keep a neutral stance on the machine and it was goofing me up. Still gotta practice more but at least I'm progressing again. Love my superjet.

You need to put more weight on your forward foot and get lower in the tray if you want to go fast without porpoising. The turn trick makes your weight shift forward so you don't porpoise momentarily. More tray time will help. Try crouching lower while putting your weight as far forward as possible.

I agree. When I first started riding, I'd put the bars into my life jacket and push my weight forward. Eventually I was comfortable enough to steer while leaning into the bars and it was also fun to slide that way. Keep trying.

Hey I’m back! Last season I was able to get a 2003 superjet with a much reduced porpoising problem. Love this thing! Right now it’s very close to stock. Rebuilt the entire driveline, including replacement of the impeller with a stock pitch Solas. Check out the vid. Not a great rider but the fast ride smooth water (non race) market seems to be untapped. That’s what I love.

ive noticed skis that have a toploader intake grate will porpoise in smoother water a higher speed. getting more forward in the tray doesnt really help it either. when i first got my ski it had a pjs toploader and porpoised like crazy. swapped to a shredmaster which has an "open" grate with no large scoop and the porpoising was greatly reduced. its some rider and some ski. many variables can affect how the ski rides

3 seconds in and I can tell your standing st the back of the tray with straight ish kegs. Get those bars down and your head over the bars and hood

Big tip a buddy told me that helped a lot was to hold the bar like I'm doing a bench press, especially at higher speeds. Keep your knees bent some more and apply forward weight/pressure. Don't feel like you're just riding the ski, feel like you're forcing it where to go and you know it's just gonna do it. In my earlier days I rode with one foot in the front corner and the other foot brought up mid-tray. As I progressed, I was able to shift my feet/weight thoughtlessly and keep the ski positioned how I wanted it, depending on speed and conditions. Over time it will come naturally and you won't strain your knees or back as much in the process.

Another thing that helped a lot was to add shims (washers) under the rear bolts of the plate. A little goes a long way! As I progressed, I took them out because it made it harder to do good wake jumps. The Jet Dynamics ride plate (extended version for my 215# self) was a lot more nimble in the turns than my previous Worx Dominator extended plate, and just as good or better at stabilizing at speed in a straight line.

Thanks for the descriptive and helpful info!
