The motor looks like its going to be making a hair over 600, while the current engine is out, Glassdave and I are going to pull the transom assbly and raise the X 2"

So right now with a 454 310 of unknown tiredness ( I have 3 seasons of laying the throttle on the dash on a used motor with unkbown hours) my absolute best has been 61.9 gps @ 4700 rpm

Person who guesses the closest to the new top speed at the end of the season wins either a handle of Morgan or a yuuugggeee supply of grape koolaid.
