      If the tachometer shows an incorrect engine RPM, the engine recognition might be wrong (especially for multi-applications). To correct this, push the 'SET' button for 10 seconds to default the engine number, then memorize each engine number again.

    What causes Yamaha 50HETO gauge response to be poor or down?
    • M
      meganriveraSep 2, 2025
