It depends on what you want. I have a '08 150 with the 155hp motor and it is plenty for me (I plan on doing all maintenance myself so not having the supercharger is a plus for me). I never had any problem getting up on plane quickly even with 4 adults on board (about 700lbs) and got a best speed of about 51mph (on gps with only myself on board on very calm, cold water). If you plan on doing a lot of wake boarding then the extra power may be better for you. You may also want the supercharged version if you plan on modding the boat alot because it is easier to improve the performance with the supercharged version - there isn't much you can do to increase the performance of the 155hp version.
With the supercharger you get a bit faster take off and a bit higher top end but end up with higher maintenance costs and higher fuel costs. Check into insurance also because you may end up having to pay more with the supercharged version.
Thanks for all the replies, I think i'll end up going w/ the 215hp.
Honestly now that I think about it, I would probably only do some tubing - not sure how intensive that is compared to wakeboarding.
[*]Harder on gas plus it uses premium vs regular
[*]More expensive to maintain (depending on how much you use it you may be rebuilding the supercharger every year or two). Winterization will also be a bit more if you live in a colder climate since the supercharger has to be protected against freezing.

I have a 155hp and wakeboard behind every weekend with ease, fist time wakeboardin i got up first try, the 155hp doesnt lack power for water sports... i was looking at the 215hp but it uses premium fuel and the 155 doesn't, also the 215 supercharger needs to be rebuilt every 100hr's. Also if you go for the 215 model change the washers in the supercharger as they can be fualty....
As for protecting the supercharger from freezing- this is the first I have heard of this- any supporting info? With the centrifugal supercharged cars I have built, freezing isn't a problem- starting them when they are freezing may be though. I'd think the same would hold true for the boat. It can get as cold and contract all it wants, as long as it is not spun to cause an interference problem. Since I don't plan on using the boat in the winter, that shouldn't be a problem. If you do have any solid info on this though, I would like to check it out. Thanks.

Rebuilt- or inspected? I thought I read inspected or at the worst, maybe new washers? If it is just the washers, that is really not a supercharger rebuild. Just curious.
I may have used my words incorrectly there. I didn't mean that you can't let the Supercharger freeze. What I meant is that the SCIC requires a bit more work when you winterize it (if you live in an area where it will freeze). It is more the intercooler that requires it since it is not self draining and you have to ensure you don't let the water remain in it for the winter. The dealer here charges a bit more to winterize the SCIC over the 155hp version.
Maybe that applies to the older boats before the closed loop cooling? As far as I know (and I admittedly haven't looked that closely, so I may be wrong), the intercooler uses the coolant water for cooling on the closed loop system. If this is the case, it should not freeze as it has antifreeze in the system as it is. If it were to freeze, it would do much more damage than just to the intercooler assembly. Again, I may be wrong, but I'll check my boat when I get it back to verify.
The supercharger cooling is part of the open loop cooling system on these boats. It uses the same water that is used to cool the exhaust. The closed loop system is only really used to cool the engine.
Yeah, if superchargers are anything like they are on cars it is only one more problem to go wrong with the boat.
