ON MY TWIN ENGINE BOAT ONE OF THE TILT INDICATORS IS MALFUNCTIONING, IT DISPLAYS 3 BARS WHEN FULLY DOWN AND ONLY 4 BARS WHEN FULLY UP.<br /> IS THER A MERCURY SWITCH IN THESE ENGINES OR SOME OTHER MECHANISM TO INDICATE POSITION? WHERE IS IT LOCATED?<br /> IS IT POSSIBLE THAT THE INDICATOR ITSELF IS MALFUNCTIONING?<br /> ANY HELP?
