New guy needs advice for his Superjet

Hi everybody,

I am new in the forum and i would like to ask your opinion regarding my new ski. I recently bought a used Superjet in excellent condition with the following mods on it:
  1. Riva plate
  2. Rive intake grate
  3. Rive exchaust
  4. Umi Handlepole
  5. Umi Steering system
  6. Hydroturf mat (which i will change to new ones)
  7. Kicker footwells.
I have bought it cause i always seen what people can do with stands ups in waves and i was amazed a lot. The reason that i got it was that many have told me if you want to race go for an SXR 800 but if you want to play then you must take a Superjet. So it was a real bargain and i got it.

What i wanted to ask is should i be aware of something regarding the hull and generally about the ski? I have read that Yamaha hulls are notorious for having an incomplete foam "air void" between the through hull rear exhaust tube and the outside edge of the hull in this area and usually damage is being created by incomplete barrel rolls. That why you need to reinforce that side of the hull

I dont know if this is true or not, thats why i want your opinion on this matter. Shall i stay with the Riva intake grate or shall i change to Worx?Also, what other stuff i can do in order to power it up????

Its the first time i have a stand up and i would like to know what i shall do in order to avoid possible problems.

Thanks for any info in advance...

PS. I do not know if this thread belongs here..

Since it is your first ski you at least got a good start. But as stated above "just ride it" after a year or so you will know what you want to do. If you try to hop it up too quick you will make it hard to ride for a beginner. So leave it alone and go ride..

Thanks for the info. The only reason i;m asking is to know if this is the right intake grate for someone to start with. But since you say so i'll go for it.....

Yup ride it as much as possible.
When I started it didn't make any difference if I had a Worx or stock intake. I still fell off.
Your on the right track. Handling equipment first. My engine is still stock and it is still plenty of power for now.

If it doesn't have a bilge then I would add one especially for the surf.

While it is cold go through and make sure all the electrical connections are in good working order and sealed with lots of dielectric grease, ebox, starter, etc.. I spent a good bit of time salt water "proofing" my ski when I bought it. So far it starts and has run quite well in the surf.

thanks for the info Scott. I didnt know that about putting this kind of grease in order to protect it from salt. It has a dual bilge pump so i think that i am ok.....The only thing i ahve to do is go and buy the rubber which is around the hood cause the old one was ruinned.

Put off mods as long as you can, once you but your first part your going too find yourself "needing" that next part and it gets pricy, this is an amazing sport your going too love it!!
So just ride it, before you ride after working on your electric clean or replace the filter inside your carb, I don't know why but mine I have too replace every year( don't worry it's super easy)

So shall i go with stock hood seals from Yamaha or shall i go for something aftermarket like the ones that you have suggested? Which is the best? Do i have to use some kind of glue for it?

You have a great hull there - there are no particular warnings to worry about. As you start to stress your ski with bigger tricks and 3/4 barrel rolls, you can start to see some cracking. The vulnerable areas are around the handlepole mount and the rear quarter on the barrel roll landing side (right side if you spin left). But I wouldn't start tearing your ski apart - you can reinforce after you start to see stress cracks in the gelcoat, if you start to see them.

In any case, one of these winters, you're going to get it into your head to returf, and then you'll figure out that if you are doing that you may as well refoam, and if you are going to do that you may as well reinforce, and if you are going to do that....

You get the idea. Ride and have fun, and when you start pounding on that pole and slamming the side of the ski against the water, keep an eye out for stress cracks. Otherwise, take the opportunity to do some reinforcement if you have torn the ski apart for other reasons.
