    Mercury 50hp Water PSI Gauge

    I would like to install a water pressure gauge on my Mercury 50hp. Where can I screw the fitting into on the motor to tap into?

    Also, is there a certain gauge kit I need to buy?

    Serial Number :
    1B455346
    Model Number:
    1050412FD

    Thanks!!
