MC X-10 Hours Help

I went and looked at an 03 X-10 yesterday. Online it showed that it had 350 hours and the dealer mentioned that as well when I was there. However, when I turned the key on the gauges lit up and under the Tach, it said 430. Is this where the hours show up on this boat?

I have an old Sea Ray, so my hours are under the engine cover attached to the actual engine, so I wanted to make sure.

Thanks
