My name is patrick and I've just purchased 2 2005 3D RFI skis. After a couple of outings, I notice they "porpoise" a bit and the jet seems to come up out of the water quite often. I've adjusted the manual "trim" in both directions bot nothing seems to fix it. Any suggestions?

Also, these skis (i have 2) seem to be quite unstable compared to others I've ridden. My wife (much less experienced than I) actually rolled it making a turn while the engine was at an idle. Is there anything I can do to increase the stability for her.


(PS - I'm in AZ and it's currently 110 and I can't wait to get out of work to ride again this evening)
