    GTX 951 DI only 4750 RPM.

    The ski was flashing MAINT and BATT LO. The rectifier was bad. I replaced that and reset the MAINT moniter. Now it just says FUEL LO, which is true. I have cleaned and tested the RAVEs and tested all the tubing to the RAVEs and the Water Valve, all OK. Also tested the RAVE solenoid, OK. Pushed the start/stop button 5 times, then put lanyard on as per manual. Then pressed start and it starts right up. Apparently this means no faults? Whether on the trailer or in the water it starts right up, idles great, runs fine to 4750 RPM then just hangs there as if rev limited. Can low fuel or old fuel cause this? What else can I check?

    Well, I've done resistance testing on all components possible as per shop manual. Everything checks out OK. I don't have the proper adapters to check fuel pressure, but I suspect that's where the problem is. The computer system is obviously limiting the RPMs to 4750. Possibly to keep the engine from running lean because of low fuel pressure. If anybody has another guess, I'm listening.
