This pwc is coming along with a lake home we are interested in...just a few general questions, like are all of these the supercharged ones I see mentioned in threads or since I do not see "supercharged" on the pwc then it is "regular", and where can I find out about what/how to adjust/etc. the various screens or info that should show up on the little display panel ? Last, it only has 7 hours on it, and it looks like new so what might it really be worth, and what oils, filters, etc. should I be concerned with checking periodically. Last one I had was a 2 stroker, and this is much different. Thanks....FRD
