This question for the Riva Crew, one of my friends has an rxp in your shop and it is there because it is only turning 8000rpms. Your shop replace the wiring harness and installed the stk supercharger blade ( it had your riva blade in it ). The ski has a stage one kit and rotax racing stk class ecu. Before the boat ran 8350 rpms and now it is only turning 8000 rpm's. He has talked to the service writer and a manager with no luck. They say it is normal. With the stage one kit alone it should turn 8100 rpms. Wondering if you could maybe help and see what is going on.

I spoke to one of our service managers. They have isolated the problem and will call your friend to discuss it with him directly.

Your comment about our saying "it is normal to be down on rpm" pretty much contradicts logic. I don't know of any service department that would state it is normal for a craft to loose performance and that it's ok. I can assure you our service department wouldn't. I'm sure it was a simple miscomuniction or misunderstanding.

Riva thanks for looking into that. When I said normal I meant they said " 8000 was were that ski was sopposed to run "
