Have an 07 pro xs 225 1B446525. When running on muffs the starboard side dump hose is hard and the port side I can squeeze it together with my fingers and feel very little water flowing through it. This is after it reaches 129* and t-stats open, temp falls to 116 and after a few seconds climbs to 123* and stays there. Is this normal or should both hoses be the same? I'm seeing 123-127 running at speed and water pressure 5-6 lbs lower than normal.
