Rx Millenium Edition

[ferkoenig]

I just purchased a 2000 RX ME (Ebay), it's top speed is only around 50mph, any suggestions on what might be the problem? As far I've read on other reviews, the top speed should be around 65mph?? Low end power seems good??

Many thanks for your ideas/suggestions,

Bill

I would change the spark plugs first to see if it has a fouled plug. I also would do a compression check and see what's going on inside. Here is some info on a compression test. You'll need a compression tester. Go to Auto Zone. I think they sell for like $25.00. The compression gage, will screw in the cylinder head in place of the spark plugs. To test compression, remove both spark plugs. Place spark plug caps on the plug cap studs near the cylinder head to ground the empty caps. This completes the circuit of the ignition electrical system and prevents any electrical problems from the caps being un grounded. Using the correct adapter for the threaded end of the tester,( same length of the spark plug threads length)screw in the tester in one plug hole. Hold the throttle wide open. Push the start button. Watch the compression gauge, when it peaks out at the most compression, let go the start button. Read the psi number. I would do it 3 times to be sure it is accurate. Check both cylinders the same way. The ideal compression is 150 psi per cylinder. If it is less, it's not a problem as long as they are close to being the same. If the psi is less than 90 it might need be time for a tear down and a rebuild. If the psi in 1 cylinder is say 140 psi and the other is 80 psi you need to tear down and repair. This difference is a lot then there is a problem.
I hope this helps you. Keep us posted on your progress.

thanks, we'll test the compression. I've read elsewhere that the fuel filter might be clogged?? Do you know how often this should be replaced? Also, the seadoo was purchased from Florida, and I ride in New Mexico with a high elevation, 4100ft, should the carbs be rejetted??

Thanks again.

Yes, that could be the total problem. 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.

I bought a manual for my 200 speedster back in January because the seadoo forum didn't have one yet for such a new boat.The seadoo dealer charged me $85.00 with a discount. The manual here is $10.95 for the month. Print off all you want. I haven't seen a better deal, plus you get one on one help, and advise.

Fixed

I finally figured out my problem, the wear ring was basically gone!! I replaced the wear ring (using instructions from here), reworked the impeller, and replaced the pump oil and it's running like new.

Good low-end power and I think good top speed for the model
Speedo: 65to70mph
Handheld GPS > 62.9mph
@ 4000ft


Thanks for all the suggestions.
