RX DI Limited RPM

[zitotc]

I've got (2) 2003 RXDI's. I am having a problem with one of them getting above 4,000rpm when in the water. "MAINT" and the red light flashes and the ski runs rough. I back off the throttle. warnings go away and all is fine below 4000rpm.

I cleaned the RAVE valves, replaced the plugs and it runs fine out of the water. Also, when I shut it off you can hear each of the RAVE valves closing so I beleive they are opening OK.

I also ran it out of the water alternating removing one plug wire and each cyclinder seems to run OK so I beleive the spark and fuel to the cylinders are OK. The nearest shop is about an hour away so I can't easily get any codes. I also disconnected power to try to reset Limp Mode in case it was activated.

Any ideas on what I can try? I will loose several weeks of water time if I have to pull it out and take it to a dealer and summer is winding down quickly.

Also, since I have the second ski I can swap parts to try to isolate the problem.

Thanks for any help you can give!

If this is a DI model you may have to swap the engine part. I hope not. Read up on all DI problems. Good luck Robin :cheers:

I believe on that model you can hit the "set" button on the info center, 5 times to get a trouble code. If you push the "Set" button for like 3 seconds it might reset the "MAINT" code if it is just a regular maintenance code, but I think it has a trouble code ...

Keep me posted.
