  Roger I am not sure which one I have but here is a picture of it that I 
have uploaded to my server.  It has
obviously been painted and is the older style with the motor coming down 
from top instead of in the side.

I'm having a hard time picturing what you are describing though (never very 
good at painting pictures in my head).
are you talking about water getting under the circular plate the shaft is 
mounted through?   Where did you find a rubber flange (or
what did you make one out of) to solve the problem?
