Abstract:
1. A system for monitoring the rotational stability of a rotating component of a device mounted to a water craft, comprising: a vibration monitoring unit having controller means, converter means, display means and data storage means; vibration sensing means, arranged to transmit a signal comprising vibration data from said rotating component to said vibration monitoring unit; rotation sensing means, arranged to transmit a signal comprising rotation data from said rotating component to said vibration monitoring unit; wherein said vibration data transmitted to said vibration monitoring unit is converted to digital data, is input to said controller means and correlated to input of said rotation data from said rotation sensing means; and, said input vibration data and said input rotation data is analyzed and compared by said controller means to model data stored in said data storage means, and said display means is enabled to display data representing the rotational stability of said rotating component at variable rotational speeds.
