I was just planning to buy and install a water pressure gauge kit for my motor. I have read that it is generally recommended to tap the line into the water hose at the top of the motor, just behind the flywheel. However, as I was reading my Mercury OEM shop manual to get more information, I found the below section that refers to a pre-existing line exiting the front of the motor (if I understand it correctly).
My Mercury shop manual covers a range of models (years and horsepowers) so I am not sure if this section applies to my motor. I don't see such a line exiting my motor at the front. Has anyone found and used this line for a pressure gauge, and if so what model Mercury motor was it used on?
Quote from Mercury shop manual:
Water Pressure Check
Water pressure may be checked by attaching a test
pressure gauge to the top of the engine block.
A water pressure line (GRAY colored) is provided
that exits at the front of the lower cowl. A dash style
gauge may be connected to this line to register water
pressure.
