I have not had any trouble out of my TC30, but I once had a jet ski and it did the same thing. The thing ran fine, but the hands would bounce all over the place. The dealer replaced the console under warrenty. This did not fix the problem. Finally, they followed the wires all the way back to the power box and found a loose connection. Tightened it up and this fixed the problem. So the initial fix cost the manufacturer about $400 when the problem was a loose nut. /forums/images/graemlins/confused.gif
