Picked up 2 SHO's on Friday. 1 Black reg and 1 Silver Cruiser.
These things are BAD!!! I have never had so much fun on a PWC.
I havent been able to do a GPS speed run yet, but speedo reads 73mph (one person or two, didnt matter, either pwc). Expect 65 to 66 mph when we get to test them.
Will throw you off on full throttle launch if you dont watch it.
The mid range response is great as well. From 50mph to full out is neck snappin awesome.
Way different than my old GPR and XLL 1200's. They are so slow out of the hole.
I dont have any real comparisons to other models as of yet. Will try to get with some of the Kawi Ultra 250's and new Sea-Doos to compare soon.

Glad to hear you love your new craft. I've only ridden them a little on our test lake, but it was enough to be impressed. I can't wait to get one out in the surf!

Let us know if and when you decide to add some more power that to that monster.
