Does any one know if there is a factory pipe plug already taped in the engine block to install a water pressure gauge? If so where is it located, I have looked but I got a feeling if its there its hiding in plain site?
my motor is a 1996 115 Johnson faststrike, 60 degree v4.
If drilling and taping my own hole is required, is it better to do it upstream of the thermostats or down stream. Thanks
