Call chuck at Extreme Marine. He can do the mechanicals for you and is very well versed in high end stuff ( skaters, formulas, hustlers, nor-techs and such ). His number is 602-749-0798. He can also refer you to someone to do a NAMS survey/appraisal oe equivalent. Here's one I found for you here in Scottsdale.
