Abstract
A boat-propeller unit comprises a carrier (4), a propeller-leg (5) and a sensor (13) which senses the angle of the propeller-leg relative to the carrier and which is intended for connection to an electrical indicating instrument mounted on the instrument panel of the boat. The sensor is of the kind which produces an output signal which varies as the distance of the sensor from an object and which is located centrally of a surface (11) on the propeller-leg, the distance of which from the sensor varies with changes in the angle of the propeller-leg relative to the carrier.
