water pressure gauge port location

[pontoon1991]

Getting ready to install water pressure gauge on 1991 Mercury 35 hp motor. Is the installation port located between the 2 spark plugs?? I have ordered a manual but haven't received it yet. Wanted to get this done before I go fishing tomorrow. Any help would be greatly appreciated.

Yes, it's a 1/8 pipe plug
