OK, I should have taken a picture before I took the impeller out (I have a picture now). The area where the impeller goes has 3 "chambers" --- the leftmost chamber is obviously the one that allows water into the pump area. There are 2 chambers of almost equal size toward the top center of the area where the impeller goes. I do not remember which chamber received the tip of the impeller. Can anyone tell me which of the 2 chambers recevies the tip of the impeller (the circular part of the impeller goes around the prop shaft). It seems like it would fit in either one. Thanks in advance. And yes, I am searching for a manual --- so far I have not found one specific to the model --- any idea in that regard would be appreciated also.
