Abstract
A method for monitoring an apparatus, such as a marine propulsion system, and determining how various measurements of indicator parameters should be compared to reference magnitudes of those indicator parameters. In addition, the method monitors the usage time of the apparatus at various operating conditions to determine whether or not calculated reference magnitudes should be used to determine appropriate and inappropriate power spectral density profiles for various indicator parameters.
