    Correct OMC Water Pressure Gauge

    I have an "89" 88hp Evinrude and wanted to install a water pressure gauge. The dealership sold me a unit that is for 1993 and Later Evinrude/Johnson Models. It is a 60 PSI gauge and I think I need a 30 PSI gauge. Will it work on my engine or should I return it and try and find the correct one?
