    2005 40hp EFI

    Engine serial:1B019138
    2005 ELPTEFI

    Engine is running fine but my analog water pressure gauge and my smartcraft gauge are not reading PSI. I am getting all other info through Smartcraft like Temp, Oil PSI, RPM, Fuel Burn... but no water PSI. Any thoughts? Even if I could just get the Analog one to work I would be happy but cant figure out why I am not getting it through the smartcraft. It is Smartcraft V3.01.

    No block pressure sensor on this engine model (water pressure).

    Check the water pressure tubing connection at the engine... disconnect it and verify there is pressure present with a known-accurate gauge.
