The present invention relates a tilt and trim sensor apparatus having a housing and a shaft rotatably mounted to the housing. The apparatus includes a magnet connected to one of the housing and the shaft. The apparatus includes a transducer connected to another of the housing and shaft. The transducer is disposed adjacent to the magnet for sensing the position of the magnet and is operable to generate an output representative of an angular position of the magnet. The apparatus has a microprocessor for sensing gauge display input requirements. The apparatus has output circuitry for outputting a signal based on the output of the transducer that is in accordance with the gauge display input requirements.
