Installing water pressure guage system - Evinrude V-4

How to install a Temperature Sensor & Gauge on Outboard Motor

I have a question maybe someone can answer. There is a fitting on the back of the block with a hose but it looks as if nothing was ever connected to it. There is low pressure water coming out of it. Trace the hose that comes off the fitting on the back of the motor. It is likely the water pressure gauge hose and may be plugged off somewhere in the engine or in the boat.

I want to make sure all is OK before I mount this on my boat. The tell tale has a good stream coming out of it. I let this motor idle for 30 minutes and the temp only reached degrees for the motor and degrees for the EMM. I have searched all over the internet for information on this connection and even the manual on the motor that came with the software with no luck.

If this is the pressure gauge connection, maybe there is an obstruction somewhere. Any help or suggestions would be greatly appreciated. Post clear focused photos of the engine block from the top, full back, and from both sides to help narrow down what motor you have. Yes, I'm pretty sure you are correct.
