1994 Merc 150 XR6 water pressure gauge hose attachment point

[dpete]

I have recently purchased a 1994 Mercury 150 XR6 (serial # 0D232030) and it has the water pickup hose for the water pressure gauge spliced into the hose that runs between the thermostats at the top/back of the block. Through reading here I've found out that is not where it should be for the most accurate readings. Where would be a better place to put that line?

My 1995 Mariner 115 had/has a plug in the top starboard side of the block. Unscrew plug, install fitting, push in hose, done. Does this XR6 have anything similar?

no such luck with a plug anywhere!.. splice it in to tha hose that runs between tha top of tha block and tha poppet.. Put a "T" right as it leaves tha top of tha block..................

Any 1/8" brass plugs screwed into the rear water jacket covers where the spark plugs are located?

Fixed! Tapped in to the hose attached to the fitting right behind the flywheel on top of the engine.
