I have a 1974 6 hp Evinrude that I just checked in a tub of water while getting it ready for the summer It ran but no water came from the "pee Hole" I made sure that there was enough water in the tub but still nothing. I only let the motor run 20 seconds at a time so not to let it get damaged from heat. Any suggestions? Do I have to start taking things apart or is there another option. Thanks Josh
