    Mercury Motor RPM and Hour print out

    2007 Mercury 250ProXS
    How can a print out on the RPM, Hour sheet be wrong? Now will explain. Got print out. At the bottom of the print out it says 567 hrs. But when I add up all the hours in all rpm ranges, it comes to 297 hours.
    What gives?
    Thanks

    Why would that have been done? New power head? Or What? Also says no Codes?

    I cleared the codes on my motor a couple of weeks ago as most of them occurred before I bought the boat. The other faults were corrected. I did not clear the engine run time history.
