Ok - first dunking of the season. Put her in and she would only manage to peak out at 25 mph and 4500 rpms. I thought it was my rave valves - took them out and cleaned them - no improvement. Bad gas - nope - changed that out as well. Put brand new plugs in. Somehow I think this is going to be expensive - any thoughts on where to begin?

The first place to begin on a di model would be to reach deep in your pocket and pull out you wallet. I hope this is not the case I just have read lot of problems with them. may be this is not the model I am thinking about. get some replies here and google seadoo di model problems and see what you come up with. the compressor comes to mind and a few other issues. this is one of the times I hope I am wrong. good luck Robin :cheers:
C-doo I think it might be the water regulator that might be causing the problem. If it is pluged it would effect the performance. Is it giving any codes, or beeps?

Quick question, what did you do to winterize it last season? That might be a better place to start.

I have read today that the water regulator can affect the rpms by as much as 800 rpms and I do not remember the speed but it was well under 10 mph this was from the most respected pwc mechanic I have seen on the internet. Now my point of view of him may differ from most people but he does seem to know what he is talking about and I have not yet seen him wrong but I am sure it has hapened more than once. :cheers:
Responses:
No codes/beeps are present
Winterization was done at dealer that has done it every year
More info:
When I changed the plugs, the one plug was extremely oily/fouled. My father in law said that he noticed smoke coming from the tail as I took off. Could too much oil cause this much of a performance drop? If so, how do I adjust this?
Thanks guys...

It could be that the plugs are fouled. Did you run it after it had no RPM's, with new plugs the second time. If not change the plugs again and see what happens. It might be just a fouled plug causing the problem. Check the water regulator also to see if it is plugged. Water leaking through that weep hole is a sign that you have blockage in the orifice connector below the regulator. Disconnect the hoses, remember which one goes where, and then un-screw it off the tank. Then, with a wrench, remove the brass fitting. This is the part that will probably be stopped up. DO NOT CHANGE the setting of this regulator. This valve can cause major engine damage if not operating properly. Clean it and reinstall it. It sounds like it is either the water regulator or fouled plugs. Keep us posted on your progress.

If it is a electrical problem it would beep a number of beeps, or indicate in the info area a fault code. That is why I asked if it did so. If it is in "LIMP MODE" it would display" MAINT" in the info center. I'm looking at the shop manual, in the seadooforum library as we speak now, looking for any info that might help. Did you see "MAINT" in the info center?
You might have to call the dealer as the MPEM (Multi Purpose Electrical Module) will have a stored code that only a dealer will be able to pull out. The manual says RAVE valves...which you cleaned, or a code. It also says it could be dirty injectors, which the MPEM will have a code for...I'll keep looking for a solution.

Did the previous owner install a new impeller? It does not have to be intentualy modifide to have the wrong pitch he could have been told it needed a new impeller and the wrong one was installed. this is just guessing good luck. robin

I would call the servicing dealer that winterized it and tell them what's going on ...it might be a freebie.
Quick question - if the MPEM has any stored code would I get any visual feedback (e.g., red light, message displayed)? I'm thinking I could be in limp mode, but there is no notification that I am. Also, what about in learning mode? Is there notification that you're using the learning key? I've never used the learning key and only have one - how do I know how its been programmed?

c-doo, sorry to hear about your problem. I have this exact problem with my 2003 RX DI and it is currently in the shop. I checked just about everything and came up with no abnormalies. Hopefully my mechanic will find a code stored in the MPEM that can help us out. good luck
C-doo...re-read post #9 and #11 in this thread... We already covered this.
The dealer is the only one that can pull the code from the mpem. It could be a legit replacement.
