1976 800 series stern drive. I am getting ready to install the rubber water pump impeller into the housing in the upper drive. It seem's like i can only squeeze 3 impellers one way and 3 the other way into the housing, need advice please, i have tried spinning it but cant see inside as what it is doing!!
