I re-read your original suggestion, and I realize that you were asking
me to check that the key-pin and the impeller are bonded together well.
When I lifted up the water pump housing to check the impeller, the
impeller stuck with the housing, and the key-pin fell off. I don't
know if this meaned the key-pin didn't bond well to the impeller or
not. Anyway, I will try what you have suggested when I get back home.

The key is a loose part. He is talking about the hub in the impeller
itself. The bond between the solid part that engages the shaft and key
breaks away from the rubber part.

If I understand this correctly, there are three things involved he
1. The brass or metal pin that is placed in the flat part of
the drive shaft and that keys into an indentation of the
hole in the middle of the impeller.
2. The white area that forms the hole in the middle of the
impeller. This is the solid rigid part of the impeller.
3. The black rubber part of the impeller, and this forms
the vanes.

I believe what you and Jim are saying that the bond between the white
solid area and the black rubber area may come loose, and this is
something that I need to watch out for. And that has nothing to do
with the metal pin.

Thanks for the explanation.

I didn't check that today because it was raining when I get back home.
I will check that in this weekend when the weather forecast will be OK
and I will someone to help me to hold on with the lower unit.
