I-6 water pressure connection

[roscoe]

I have an I-6 115 hp 1986, that I would like to add a water pressure gauge to.

Where is the easiest location on these motors to connect pressure tube ?

There used to be a pipeplug on the cylinder water jacket cover.----Seems that would be easy.

If no plug on the waterjacket over the cylinder head, use a brass tee to replace the telltale elbow fitting. Plumb the telltale and water pressure gauge to the tee. Use a 0-15PSI gauge, as the water pressure is pretty low.
