Can anyone tell us the location of the Water Pressure Sensor on the engine?

Got Smartcraft alarm "BLK PSI CKT HI". From what we've read online it appears it might be a faulty pressure sensor.
 
It is on the top of the heat exchanger on the back side of the engine over the transmission. Follow the cooling hose from the raw water pump. I carry spares they are a common failure. If you are ever in dire need and know it's the sensor that fails you can disconnect the connector and it will take you out of limp mode.

Thanks Jaay757. Found it. Tomorrow we'll swap the sensor from starboard engine. Hopefully it's only a faulty sensor.
 
Mucho tnx for the discussion! I was wondering where the pressure sensor was.
Fair winds and following seas to all.
