4K views · 587 reactions | The 500R outboard is equipped with a new sensor located in the intake attenuator to measure the humidity level of the incoming air. This allows the engine ECM to combine reported humidity with air pressure and air temperature data to determine the ideal spark timing for prevailing conditions. Boaters will notice a significant gain in power in challenging, very humid conditions. #500R #WideOpen #mercuryracing | Mercury Racing | Facebook
