"I have a 73 merc 50hp, when i got it the water flow at the pee hole was very week at high rpm's, and nothing at idle, but never over heated. I put a new inpeller kit in, (ie impeller, upper and lower housing, gaskets ect)and now I have very good flow at high rpm, but still no flow at idle at the pee hole, only out of the exhust. And still the engine does not overheat. I have tested the over heat switch and it works properly. Is this correct opperation for this year of an engine? Any input would be great. Thanks"
