Got to take it out on my maiden voyage this past weekend. Very happy with the performance of the SPS package. Handles very well and rides very well. I was able to get 38.2 MPH on GPS with four people on board and full tank of gas. This is with the Merc 150 and the Enertia 15 x15 stainless prop. Thoughts on the speed? Yes it only has 1.5 hours on it, so I know once it is broken in may get a little more. I did forget to look at what RPM's it was pulling though.
