    Take the line off the top of the rudder and blow through it. If you can't, there is a blockage somewhere. What's with the T fittings? The way you have it set up the water is blowing right past the motor and out the discharge! Get rid of those "T's"! Run from rudder through esc to motor, through motor and out! Period!

      Water takes the easiest route so with that being said all the "t" connectors you have maybe part of your issue. Get rid of those connectors and run the water line to the esc 1st then to the motor or mount then motor. Just have cooling to the esc first. Take a small rat or round file and slightly enlarge the opening in the rudder. First step is to dump those connectors though. Take the cooling line off the top of the rudder and blow through it make sure you feel air coming threw the outlet.

          Start by eliminating those "T" joints.
          Route it as such: Pickup to ESC - ESC to Motor - Motor to outlet

          Post a pic of the opening in the rudder blade please...

            Take off the hose at the top of the rudder and enlarge the rudder pickup with a small round file and blow of the shavings. Don't blow out the shaving with the hose attached because small pieces of debris can get blown into the line causing a blockage later.

                Try the T-pieces this way it looks like you dont have them flowing the right way

                  You don't need the T's at all! Get rid of them! Take off the tubing from the rudder and blow through it! Is it clear? I wouldn't booger up that rudder! Most likely the opening's fine. I have NEVER had to enlarge one.

                      You never answered whether or not you can blow through the system? If not, then there is a blockage. If you can, then it should be working. Why do you say it's not working? Have you run the boat?
