I have a 1975 Johnson 115 (115ETL75E) that apparently uses what has been called a "rare" two outlet water pump housing. I can't seem to find the housing anywhere.<br /><br />Is there a retrofit available...or do I just reuse the old housing and hope for the best? I have the service manual for this engine, but can't find any specs for the water pump housing.<br /><br />I understand that there is a lot of flex in the impeller blades, and I understand the displacement/centrifugal nature of the pump...but since I don't know how thick the walls are supposed to be...or how wide the opening is supposed to be, I don't really know how to tell if the housing is okay to reuse or not.<br /><br />$0.01 for your thoughts,<br />Joe
