I have a 1992 Johnson 225hp, which had no water coming out of the pee tube while running on a hose with muffs, even though the impeller had been replaced recently. I put in a new water pump (housing, impeller, etc.) and am still not getting water coming out of the pee hole. I checked all the hosed for obstruction, checked the stats, etc. I even tested it on a hose with muffs with the thermostats removed, but got no water coming out of the thermostat cavities. I'm stumped after twice removing the lower unit and checking the water pump, and still getting no water... Please help!!!!
