Water pressure gauge

[Newbie600rr]

I have a new 2015 60hp Mercury that I am looking to add a water pressure gauge to. Mercury recommends teeing at the fuel cooler line but really don't want to tee anywhere if I don't have to. Looking at some past posts, came across a post to put it in a port by the thermostat housing. Wondering if this will work for my motor. I included a pic of where I think it might go.

Go to a parts page, and look up that plug, it may indicate that plug as water pressure location. Or, go to mercury dealer and ask if it is the right place. They should tell you.
I'm not familiar with your motor (too new). Likewise, asking dealer, you want to know it won't upset your warranty - very important to know this.

They may also tell you if your wire harness has wiring for the pressure sensor, may have plug for it.

Good luck.
