The boat i'm lookin at is an 04. Twin step with staggered 525's. The deck and the windshield are the only apparent differeces. The mph should be the same.

I believe the old "Fever" is the "Lightning"......I believeThe Executioner is narrower (cockpit) becuase it has a walk around area on the deck (like a sonic)

Here's a picture of an Executioner

Here's a picture of the Fever............wider cockpit...........look at the side above the rubrail and you can see the difference in the boats.

O4 is not the same bottom as 2005.
