Power loss

[wojtyla11]

Hi everyone,
I have just rebuilt my 2005 RXT engine after a supercharger failure which smashed my engine to bits, took it out on the lake yesterday to start running it in again but the revs keep jumping from 3000 to about 5000rpm when the throttle is pressed in about half way then it clears and ski runs normal for about 5mins then it happens again, also im getting a check engine warning after about 5mins then ski only revs to 5000rpm no more when the ski failed that message showed on the clocks do I have to take it to a dealer to have the fault codes cleared? thanks everyone.

Faults will clear when the problem is fixed. Sounds like you have issues going on. maybe overheat.

On lake yesterday for 5hrs no overheating, I kept a very close eye on engine temp on the clocks ran between 51 - 53.

What was the code??

It just said check engine? The ski has been in the garage for 2 years only now got around to fixing it, I thought it might need a good blast to clean and clear everything?

e temp on the gauges is external air temperature, not engine temperature.
