Abstract
A boat propeller drive unit, a so-called inboard-outboard drive unit, has a sensor which senses the trim/tilting angle of the drive unit and is designed to be connected to an electrical indicator instrument on the boat instrument panel. The sensor is a potentiometer mounted in a recess in the drive unit steering shaft. A shaft mounted in a bore in the steering shaft engages the potentiometer and is joined at its lower end to a gear, which engages a toothed segment on the helmet of the drive unit. When the drive unit is tilted, the gear is rotated by the toothed segment, and the output signal of the potentiometer varies.
