Abstract

See full text

A pitch angle indicator system indicates a pitch angle of blades of a propeller of a marine propulsion unit. A mechanical link couples at least one of the blades to a first end of a first rod. An indicator is coupled to a second end of the first rod. The mechanical link is configured to convert a change in the pitch angle into a rotation of the first rod about its longitudinal axis. The indicator is configured to provide an indication of the amount of rotation of the first rod about the longitudinal axis.
