Pics of my new GTX!!

[Rampage]

Took it out today...what a great ski!! I think its needs some very minor tuning on the carbs...but other than that, everything works great...even all the gauges. Every single inch of it is almost perfect. :cheers:

Good luck with it!

Wow, that does look clean! What do the GTXs top out at? A great score all around!

 

[RFoster130]

Nice lookin ski. Very clean. So did ya get it for an even trade?

 

[Rampage]

I made money LOL!! Peak speed I have seen on this one was 56.

 

[RFoster130]

Thats awesome you started with your GTI and managed to work it to get the GTX you wanted and made money. :cheers:

 

[Fastnature]

Holy smokes that is clean.. I wish the one i just picked up was that clean. Good trade

 

[djredman99]

Certainly looks to be in great shape. Glad everything worked out for you!

Well we took it out Sunday. Everything went great, except on the way back from the island...I crused out about 53 and about half way back it would not go over 40...I think I may have gotten into some seagrass though...when I got back to the boat ramp and shut it off there was lots of grass floating out from underneith the ski. I reached under it to clear out the great but there was not much in there. I think it came out when I shut it off. I did not have time to go back out to see if that was the issue. The only other thing I noticed was about mid throttle and cruising, the rpms seem to fluxuate...feel almost like I give it a little more throttle on and off....other than that everything is great and I'm soooo excited I finally got my GTX!!! :cheers:

Quick update....Took it out Friday..Def needs a wear ring, and somthing is up at wide open throttle cruising...RPM's drop about 1,000 then back up...almost consitant...Starts up very easy, and when you mash the throttle it does not hesitate or anything.

Are you sure that wasn't the RAVE valve's opening up?

If you ride the throttle in just the right place the rave valves will open and shut, it's kind of weird at first.

Speaking of RAVE valves, make sure you take them apart and inspect/clean them before too long, since you don't when it was done last, they could be in need of service.

Thanks for the info..do you have a linky on how to do those?

It's pretty simple. Do you have the operators guide & service manual for your ski?

Also check out http://www.seadooforum.com/showthread.php?t=33247 for some basic information about cleaning RAVE valves.

You can also do a google search and find alot of information.

The basics is to remove the RAVE valves, clean the carbon off, inspect the bellows to make sure there are no holes/wear, and reassemble.

Here's a post from kustomkarl on RAVE Valves...

Here is some information to the annual cleaning of the RAVE valve;
The RAVE, (Rotax Adjustable Variable Exhaust) valves are located above the exhaust valve. There are 2 of them per engine. They are round with a red adjustment screw in the middle. It has a clip that holds it together. How they work is that they open the exhaust port larger as the engine rpm's increase. When the rpm's drop down so do the RAVE valves. They work on the principle of the pressure of the exhaust system. Rpm's increase, pressure increases and the valve opens, rpm's drop pressure drops, Valve closes. They should be de-carbonized annual. To disassemble the rave valves, remove the spring clip on top, remove the black cover. There is a spring under the cover. Remove the piston by turning it with a metric socket. On the bottom of the piston is the rubber "Bellows" be careful with the small retaining spring that hold the bellows on the piston. Remove the 2 allen screws that hold the base on the cylinder. Remove the base and gasket. The long valve won't fall in the cylinder just pull it out. There is an o ring under the base, on the shaft of the guillotine valve. Be careful to see how it came apart as it has to go back together that same way again. On the base, notice the notch that it is facing down. Clean all the carbon off the guillotine valve. I use carb cleaner and 400 grit paper. Check the bellows for any small pin holes. If so replace it. If not, reassemble it on the clean guillotine valve, and install it back on the engine the same way it came apart. The guillotine valve only fits one way. The one closest to the exhaust pipe will come off differently then the other one. You will have to remove the allen screws and turn the base so it clears the exhaust pipe. I would do one at a time in case you forget how it goes back together again. This way you can look at the other one and copy it. Do both engines 2 per engine. Take your time and if you have questions give us a shout. We'll be here to help you out.
If the RAVE valves are dirty it will not rev up correctly and could be causing your problem.

The adjustment knob (the red cap) should either be screwed all the way in or flush to the top of the black ring of the cap. This will only affect performance, as far as how it jumps out of the hole or how well it runs for extended periods at WOT.

Do you have a seadoo shop manual? If not here’s an idea for you. You could join as a "premium member". As a premium member you can down load a authentic seadoo manual from the seadoo manual library. In the library is a variety of manuals for almost all years and models. You can view as many as you like on line as a PDF file, or download it and print it for your personal and private use. There are operator manuals and repair manuals for you to do your own repairs on your seadoo. The repair manuals have everything from troubleshooting, repair procedures to winterizing. It contains wire diagrams torque specs and pictures for disassemble and assemble instructions. In the spec sheets it tells everything needed to maintain oil changes, spark plug gaps, carburetor rebuilds and impeller wear ring tolerances. Click on the "Seadoo Manuals" link at the top of the page for more details. If you need any help or get in a jam, we are always here to answer your questions too. Premium members get priority when it comes to getting quick detailed answers.

Hey

How does the ski feel after cleaning the RAVE valves. Is she running smooth now. On your exhaust that goes from the black water box to the outside is that rubber or stainless steel. Mine is stainless steel and seem bigger than the other jetskis, but i haven't been able to compare to other seadoo ski's as where i stay it is yamaha and kawasaki country.
The farmers here all follow one trend. All drive Toyota's, drink brandy & coke.

Mine is rubber. I might take it out today. I cleaned the valves, and I replaced the gasket from the manifold to the mid pipe.

Hey Rampage - is that a seadoo leaping those waves on your avatar?

If so - how can I see a larger pic of that?

By the way, I'm pretty sure it's the RAVE valves causing that. I have the
same seadoo, The first one seems to have this issue often so I have
to keep an eye on them. The 2nd one I have seems to go longer without
an issue.
