Since I owe more than I think I can get for my boat I cant trade/sell to up grad on a new boat.. So I have recently been looking around on what I can do to my boat to get some more MPH. My goal is to hit 80, currently I can get 70 max on perfect conditions. I have just recently heard about blue printing, not sure what it is and getting a lab prop. ( current prop is the stock 4 blade that comes with the 496HO ) Anyone care to point me in the right direction on what I need to do to hit the 80s and a idea on the cost? Anyone knwo of any good boat performance shops in Lake Havasu City?
