What should a 2001 28 Daytona tall deck with 540 ci. 625hp a side run for speed. It has imco extention boxs and 1.5 gears with 32 labbed props

125 - 130mph @ 6400rpm if it does have that gear ratio and makes that power.

115-120 tall decks were not as fast of a hull. Lots of variables x dimension altitude, humidity ect.. I have worked on a tall deck with 700hp supercharged motors that ran 118. But I had the porpoise syndrome.
